Answer:
(b) a[1] = -7, a[n] = a[n-1] + 3
Step-by-step explanation:
Comparing the given formula to the general form for the n-th term of an arithmetic sequence ...
an = a1 +d(n -1)
we see that the first term (a1) is -7, and the common difference (d) is +3.
The recursive version of the sequence definition is ...
a[1] = a1
a[n] = a[n-1] +d
So, the appropriate choice is ...
a[1] = -7, a[n] = a[n-1] +3
