Q. At time k=0, an initial investment of $1200 is made into a savings account that pays % interest compounded monthly. (The monthly interest rate is 0.0025.) Each month, after the initial investment, an additional $200 is added to the account. Let Yk be the amount in the atcount at the end of k months.

**Question:**
At time \( k = 0 \), an initial investment of $1200 is made into a savings account that pays 3% interest compounded monthly. (The monthly interest rate is 0.0025.) Each month, after the initial investment, an additional $200 is added to the account. Let \( Y_k \) be the amount in the account at the end of \( k \) months.
a. **Write the difference equation satisfied by \( Y_k \)**
\[ Y_{k+1} = \_\_\_\_\_\_\_\_\_\_ \]
\[ Y_0 = \_\_\_\_\_\_\_\_\_\_ \]
b. **Determine the following:**
- The amount of money that will be in the account after 3 years is $ \_\_\_\_\_\_\_\_
- The amount of money that will be in the account after 4 years is $ \_\_\_\_\_\_\_\_
- The amount of money that will be in the account after 6 years is $ \_\_\_\_\_\_\_\_
