Question

Jamal puts $2300 into an account that does not earn any interest.

Every month after that, he deposits the same amount of money.

This sequence
represents his account balance for the first few months:

$2300, $2500, $2700, ...


What is the explicit formula for the amount of money in his account at the beginning of month n?

A. a(n) = 2300 + (n − 1)200

B. a(n) = 200-2300"-1

C. a(n) = 2300 200-1

D. a(n) = 200+ (n − 1)2300

Answer 1

The explicit formula for the amount of money in his account at the beginning of month n is  a(n) = 2300 + (n − 1)200.

What is the explicit formula?

The explicit formula would be a linear function. A linear function is a function that has a single variable raised to the power of 1.The rate of increase in the account is a constant amount : $200

Amount of money at the beginning of the  month = beginning balance + (number of months - 1) x rate of increase

a(n) = 2300 + (n − 1)200
