Question

Write an explicit formula for the recursive formula.

A(n) = A(n-1)+ 4.8; A(1)= 7.2
Choose the correct formula below.
O A. A(n) = 7.2+(n - 1)4.8
OB. A(n)=4.8+ (n - 1)7.2
O c. A(n) = A(n-1) + (n-1)4.8+ 7.2
O D. A(n) = 7.2 +4.8n

Answer 1

Answer: A

Explanation:

We can recognize this as an arithmetic sequence with first term 7.2 and common difference 4.8
