Question

the first term in the sequence is 38. each following term is found by subtracting 7 in the previous term. find the third term?

Answer 1

24

Explanation:

This is a simple sequence, and they are asking only for the third number in the sequence, so repeated subtraction using is the optimal method for solving for the final answer.

First start with the first term in the sequence, which is 38. The next term is found by subtracting 7.

2nd term = 1st term - 7 (original equation)

2nd term = 38 - 7 (substitute values)

2nd term = 31 (combine like terms by subtracting)

Then repeat this process to find the third term.

3rd term = 2nd term - 7 (original equation)

3rd term = 31 - 7 (substitute values)

3rd term = 24 (combine like terms by subtracting)

Therefore the third term is 24.
