Answer:

2. a1 = 10 and an = a(n-1) + 2

Step-by-step explanation:

10 is our first term so it would be a of 1.

Then, in this arithmetic sequence, it is increasing by 2.

So, therefore our recursive formula for this arithmetic sequence would be:

a(n) = a(n-1) + 2

Answer:

It's (2).

Step-by-step explanation:

The first term a1 = 10 and the common difference  is 12 - 10 = 2.

So it is  a1 = 10 and an = a(n-1) + 2.
