The expression 1.02^ (4+n) can be used because 1.02^4 * 1.02^2 = 1.02^ (4+n) AND this is option C.

Step-by-step explanation:

For 4 + N years = (1 + 2/100) ^ (4+N)

= 1.02 ^ (4+N)

Remember, that the number of years is increased by N and interest rate remain the same, and n is years, and which is now 4 + N.
