Answer:
a[1] = -10
a[n] = 12 + a[n-1]
Step-by-step explanation:
First differences are ...
- 2 -(-10) = 12
- 14 -2 = 12
- 26 -14 = 12
A constant first difference of 12 means this is an arithmetic sequence. Each term is 12 more than the previous, so the recursive rule is ...
a[1] = -10
a[n] = 12 + a[n-1]
