The explicit formula for a particular arithmetic sequence is an = 8 + (n - 1)3, with n > 1
What are the first three terms?
ai -
11
az
a3 =

8, 11, 14

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given

= 8 + (n - 1)3 , then

a₁ = 8 and d = 3 , thus

a₂ = 8 + 3 = 11

a₃ = 11 + 3 = 14

The first 3 terms are 8, 11, 14
