Answer 1

ANSWER

The explicit formula is :

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

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,

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