Question

Check all that apply in regards to the given sequence:
5, 8, 11, 14, 17, 20, 23, ...

Answer 1

Common difference is 3

Answer 2

see explanation

Explanation:

There is a common difference d between consecutive terms, that is

d = 8 - 5 = 11 - 8 = 14 - 11 = 17 - 14 = 20 - 17 = 23 - 20 = 3

This indicates the sequence is arithmetic

The common difference d = 3

The first term a₁ = 5 and

a₈ = 23 + 3 = 26
