Chapter 5: Problem 22

Find each sum. \(13+(-5)\)

Short Answer

Expert verified
The sum of 13 and -5 is 8.

Step by step solution

01

Identify the numbers

First, identify the two integers that are given in the exercise. Here, the two integers are 13, which is a positive integer, and -5, which is a negative integer.
02

Understand the operation

The operation here is a sum between a positive and a negative integer, this could be interpreted as a subtraction, because the sign of the second number changes when added to the first number. So, the operation can be viewed as \(13 - 5\).
03

Compute the operation

Finally, execute the subtraction operation as obtained from understanding, i.e. subtract 5 from 13. The result of this operation is 8.

Determine whether each statement makes sense or does not make sense, and explain your reasoning. There's no end to the number of geometric sequences that I can generate whose first term is 5 if I pick nonzero numbers \(r\) and multiply 5 by each value of \(r\) repeatedly.

Find the indicated term for the geometric sequence with first term, \(a_{1}\), and common ratio, \(r\). Find \(a_{100}\), when \(a_{1}=50, r=1\).

Determine whether each sequence is arithmetic or geometric. Then find the next two terms. \(-9,-5,-1,3, \ldots\)

Find the indicated term for the geometric sequence with first term, \(a_{1}\), and common ratio, \(r\). Find \(a_{6}\), when \(a_{1}=-2, r=-3\).

Write the first six terms of the geometric sequence with the first term, \(a_{1}\), and common ratio, \(r\). \(a_{1}=-8, r=-5\)
