Answer:
g(n) = - 29
Step-by-step explanation:
Given the recursive formula
g(n) = g(n - 1). - 4
This tells us that to obtain a term in the sequence we multiply the previous term by - 4.
We are dealing with a geometric sequence with explicit formula
g(n) = g(1)
Here g(1) = - 29 and r = - 4, thus
g(n) = - 29 ← explicit formula
