Answer:

g(n) = 2n +49

Explanation:

The recursive formula tells you this is an arithmetic sequence with first term 51 and common difference 2. The explicit formula for such a sequence is ...

an = a1 +d(n -1) . . . . first term a1, common difference d

Using the sequence values, we have ...

g(n) = 51 +2(n -1)

g(n) = 2n +49 . . . . . simplified
