Future Value Calculation

[KWF]

Hello:

I have a question regarding the following compound interest and future value calculation.

Year 1 P + rP equals balance after the first year.
Year 2 (P + rP) + r(P + rP) equals balance after the second year.
Year 3 ? equals balance after the third year.

What would follow for year three?

I thank you for your reply.

Hello:

I have a question regarding the following compound interest and future value calculation.

Year 1 P + rP = P *(1+r)¹ equals balance after the first year.
Year 2 (P + rP) + r(P + rP) = P*(1+r)*(1+r) = P*(1+r)² equals balance after the second year.
Year 3 ? [(P + rP) + r(P + rP)] + r [(P + rP) + r(P + rP)] = P*(1+r)³ equals balance after the third year.

What would follow for year three?

I thank you for your reply.
