Nola Stokes · Answer 1

a (n) = 7 + 3 (n - 1)

Step-by-step explanation:

Notice that every term of the sequence 7, 10, 13, 16 is 3 more than the previous term. That tells us this is an arithmetic sequence with first term 7 and common difference (d) 3.

Adapting the given equation, we end up with

a (n) = 7 + 3 (n - 1)
