To Write: The equation for the given sequence and to find the indicated term.

Answer to Problem 19PPS
The equation that describes the sequence is
Explanation of Solution
Given information:
Term number (n) | 1 | 2 | 3 | 4 |
Term (t) | 16 | 17 | 18 | 19 |
Calculation:
The terms have a common difference of 1. The term is 15 more than the term number. So the equation that describes the sequence is
Use the equation to find the 23rd term. Let
Write the equation
Substitute the value of n i.e. 23
Add 23 and 15 i.e. 38
Thus the 23rd term is 38.
