1.013=r^4

r=1.013^.25

F=2500(1-(1.013^.25)^n)/(1-1.013^.25)

F=2500(1-(1.013^.25^100))/(1-1.013^.25)

F=294606.19

So the answer is C. $294847, (they must have done intermediate rounding which leads to the slight discrepancy)

Step-by-step explanation:

First term = a =4

Common difference = d = 2nd term - first term

d = 8 - 4 = 4

Last term = l = 400

First we have to fin the number of terms 'n'

l = a + (n-1)d

4 + (n-1)*4 = 400

4 + 4n- 4 = 400

      4n = 400     {Divide both sides by 4}

         n = 400/4

n = 100
