Solve the Problem $\mathrm { a } _ { \mathrm { n } } = 7000 \left( 1 + \frac { 0.08 } { 4 } \right) ^ { \mathrm { n } } \quad \mathrm { n } = 1,2,3 , \ldots$

Solve the problem.
-A deposit of $7000 is made in an account that earns 8% interest compounded quarterly. The balance in the account after n quarters is given by the sequence $\mathrm { a } _ { \mathrm { n } } = 7000 \left( 1 + \frac { 0.08 } { 4 } \right) ^ { \mathrm { n } } \quad \mathrm { n } = 1,2,3 , \ldots$
