Question

Using the variable n for the term, describe the sequence.

Answer 1

3 + 5n

Explanation:

This is an arithmetic sequence.

First term = a = 8

Common difference = d =Second term - first term

= 13 - 8

= 5

Nth term = a + (n- 1)*d

= 8 + (n -1) * 5

= 8 + n*5 - 1 *5

= 8 + 5n - 5

= 8 - 5 + 5n

= 3 + 5n
