FV = P * [((1 + r)^n - 1) / r]
where:
P is the amount of each payment ($1,250 in this case),
r is the interest rate per period (7% or 0.07 in this case), and
n is the number of periods (3 years in this case).
Substituting these values into the formula gives:
FV = $1,250 * [((1 + 0.07)^3 - 1) / 0.07]
FV = $4018.63
