Answer 1

The explicit formula is :

`a_n = 8+ 3(n - 1)`

Step-by-step explanation

The given sequence is

8,11,14,17,20,23,26,...

The first term is

`a_1=8`

The common difference is

d=11-8

d=3

The explicit formula is given by:

`a_n = a_1 + d(n - 1)`

We substitute the values to get,

`a_n = 8+ 3(n - 1)`
