Chapter 8.4, Problem 27SR

To determine

To describe: the given sequence using words and symbols

Answer to Problem 27SR

The equation that describes the sequence is $t=3n-2$ .

Explanation of Solution

Given:

Consider the sequence: $1,4,7,10,\dots$

Calculation:

In the sequence, the terms have common difference of 3.

And, a term is 2 less than thrice the term number. It means that the equation of sequence is:

  $t=3n-2$

Conclusion:

Therefore, the equation that describe the sequence is $t=3n-2$ .
