Chapter 13: Problem 15

List the first five terms of each sequence. \(\left\\{s_{n}\right\\}=\\{n\\}\)

Short Answer

Expert verified
1, 2, 3, 4, 5.

Step by step solution

01

Understand the Sequence

The given sequence is \(\right\{ s_{n} \right\}=\right\{n\right\}\right\). This notation means each term in the sequence is equal to its position number (n).
02

Identify the First Term

For the first term, set \(n = 1\). Hence, \(s_1 = 1\).
03

Identify the Second Term

For the second term, set \(n = 2\). Hence, \(s_2 = 2\).
04

Identify the Third Term

For the third term, set \(n = 3\). Hence, \(s_3 = 3\).
05

Identify the Fourth Term

For the fourth term, set \(n = 4\). Hence, \(s_4 = 4\).
06

Identify the Fifth Term

For the fifth term, set \(n = 5\). Hence, \(s_5 = 5\).
07

Final Answer

The first five terms of the sequence \(\right\{ s_{n} \right\}=\right\{n\right\}\right\) are 1, 2, 3, 4, and 5.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Sequence in Mathematics
A sequence in mathematics is a list of numbers arranged in a specific order. Sequences are essential concepts that appear in various mathematical topics, ranging from basic arithmetic to complex calculus.
An important property of sequences is that they are ordered sets, meaning position and arrangement matter.
Here, we focus on identifying and listing sequence terms.
For example, in the sequence \(\right\{ s_n \right\} \), each term follows a specific rule. Understanding this rule is crucial to determining any term's value.
Terms in a Sequence
Terms are the individual elements or numbers in a sequence. Each term has a specific position or order within the sequence.
  • For instance, the first term is often represented as \(s_1\), the second term as \(s_2\), and so on.
  • In the sequence \(\right\{ s_n \right\}=\right\{ n \right\}\), each term is equal to its position number.
This implies that:
\(s_1 = 1\)
\(s_2 = 2\)
\(s_3 = 3\)
\(s_4 = 4\)
and \(s_5 = 5\). Listing these terms correctly is key to mastering sequences.
Position Number in a Sequence
The position number in a sequence indicates the location of a term. It is represented by \(n\) in mathematics.
  • For the sequence given, \(\right\{ s_n \right\} \), the position number is essential in determining the value of each term.
  • When \(n = 1\), the first term is \(s_1 = 1\).
  • When \(n = 2\), the second term is \(s_2 = 2\).
Hence, by knowing the position number \(n\), you can identify any term within the sequence, making it an integral part of understanding and solving sequence problems.

Challenge Problem Paper Creases If a sheet of paper is folded in half by folding the top edge down to the bottom edge, one crease will result. If the folded paper is folded in the same manner, the result is three creases. With each fold, the number of creases can be defined recursively by \(c_{1}=1, c_{n+1}=2 c_{n}+1\) (a) Find the number of creases for \(n=3\) and \(n=4\) folds. (b) Use the given information and your results from part (a) to find a formula for the number of creases after \(n\) folds, \(c_{n}\), in terms of the number of folds alone. (c) Use the Principle of Mathematical Induction to prove that the formula found in part (b) is correct for all natural numbers. (d) Tosa Tengujo is reportedly the world's thinnest paper with a thickness of \(0.02 \mathrm{~mm}\). If a piece of this paper could be folded 25 times, how tall would the stack be?

You are interviewing for a job and receive two offers for a five-year contract: A: \(\$ 40,000\) to start, with guaranteed annual increases of \(6 \%\) for the first 5 years B: \(\$ 44,000\) to start, with guaranteed annual increases of \(3 \%\) for the first 5 years Which offer is better if your goal is to be making as much as possible after 5 years? Which is better if your goal is to make as much money as possible over the contract (5 years)?

Prove each statement. $$ \begin{aligned} &a-b \text { is a factor of } a^{n}-b^{n}\\\ &\text { [Hint: } \left.a^{k+1}-b^{k+1}=a\left(a^{k}-b^{k}\right)+b^{k}(a-b)\right] \end{aligned} $$

Use the Principle of Mathematical Induction to show that the given statement is true for all natural numbers \(n\). $$ 1+3+3^{2}+\cdots+3^{n-1}=\frac{1}{2}\left(3^{n}-1\right) $$
