Question

Please help me out, I’m on my last question :(

Answer 1

Option C

Explanation:

The first term of the sequence is -7.

`a_1=-7`

The common difference is +6.

`-7+6=-1\\-1+6=5\\5+6=11`

`d=+6`

Therefore, the answer is option C.

Answer 2

C

Explanation:

Since the first term of the sequence is -7, and each next term is 6 larger than the previous one, the recursive function would be:

`a_1=-7 \\\\a_n=a_(n-1)+6`

This matches up with answer choice C. Hope this helps!
