91Ó°ÊÓ

Identify a pattern in each list of numbers. Then use this pattern to find the next number. (More than one pattern might exist, so it is possible that there is more than one correct answer.) \(1, \frac{1}{2}, \frac{1}{3}, \frac{1}{4}, \frac{1}{5}\),

Short Answer

Expert verified
The sixth term in the sequence is \(\frac{1}{6}\)

Step by step solution

01

Identify the Pattern

Start by identifying the pattern in the given sequence. We can simply observe that the sequence is all fractions with the numerator as 1, and the denominator increasing by 1 with each new number. So, the pattern is \(\frac{1}{n}\), where \(n\) is a number that increases by 1 with each new term in the sequence.
02

Apply the Pattern to Find the Next Number

Apply this pattern to find the next number in the sequence. So if the fifth term in the sequence is \(\frac{1}{5}\), implying that \(n=5\), for the fifth term, then the next term, which is the sixth term, should have \(n=6\). So the sixth term should be \(\frac{1}{n} = \frac{1}{6}\).

Key Concepts

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

Sequence Identification
When solving a problem surrounding sequence identification, a student must examine how the numbers in the series are related to each other. To do so, observe each term and compare it to the previous ones. Sometimes, recognizing the pattern requires examining the differences between terms or the ratios if they're fractions.

An essential exercise improvement advice would be to practice with different types of sequences, such as arithmetic, geometric, or more complex patterns, and use real-world examples. For example, in the provided sequence (1, \(\frac{1}{2}\), \(\frac{1}{3}\), \(\frac{1}{4}\), \(\frac{1}{5}\))n(1, \(\frac{1}{2}\), \(\frac{1}{3}\), \(\frac{1}{4}\), \(\frac{1}{5}\))n the pattern is the count from 1 to infinity in the denominator of a fraction that always has the numerator of 1.
Fractional Sequences
Dealing with fractional sequences involves understanding not just whole numbers but also the concept of parts of a whole, as captured by fractions. The sequence in our example is a straightforward one, where each term is a fraction consisting of 1 over an incrementally increasing natural number.

To improve skills in identifying and continuing fractional sequences, one could explore various common patterns, such as sequences where the numerators, the denominators, or both, follow a particular arithmetic or geometric pattern. Knowing these basic patterns can help when sequences become more complex. For instance, a sequential pattern of fractions might involve alternating sequences or patterns that require combining multiple mathematical concepts.
Mathematical Reasoning
Mathematical reasoning is the glue that holds together the process of identifying sequences and predicting their continuity. It involves logical thinking, hypothesis testing, and proves or disapproves assumptions based on mathematical theories. When applying mathematical reasoning to sequences, one typically first forms a conjecture about the pattern based on observed properties.

For students looking to enhance their mathematical reasoning, it is advisable to attempt different problems, including those that involve indirect or less obvious patterns. Furthermore, it's crucial to not only find the pattern but also to justify why the identified pattern holds true for the sequence. This might include articulating the rule behind the pattern or proving it using algebra.
