How can you determine the type of annuity using a financial setting on a GDC?

• A. By setting the interest rate to zero
• B. By changing PMT to either END or BEGIN
• C. By selecting an amortization option
• D. By entering the principal amount

Answer: (B)

To determine the type of annuity using a financial setting on a graphical display calculator (GDC), you can adjust the payment timing parameter to either END or BEGIN. This is essential because annuities can either be paid at the end of each period (ordinary annuities) or at the beginning of each period (annuity due). By changing the payment type in the GDC settings, you effectively specify the frequency and timing of the cash flows, which distinguishes between these two types of annuities. When the payment is set to END, it indicates that the payments are made at the end of each interval, typical for ordinary annuities. Conversely, when set to BEGIN, it indicates that payments are made at the start of each interval, characteristic of an annuity due. Therefore, this adjustment provides clear insight into the nature of the annuity being calculated or analyzed. The other options do not provide a definitive measure of the annuity type. Adjusting the interest rate or entering the principal amount does not inherently affect whether the payments are made at the beginning or the end of the periods. Similarly, selecting an amortization option pertains to how debt is repaid over time rather than directly identifying the type of annuity. Thus, changing
