Sequences and Their Notations · Exercise 62

Follow these steps to evaluate a sequence defined recursively using a graphing calculator:

• On the home screen, key in the value for the initial term $a_{1}$ and press [ENTER].
• Enter the recursive formula by keying in all numerical values given in the formula, along with the key strokes [2ND] ANS for the previous term $a_{n - 1} .$ Press [ENTER].
• Continue pressing [ENTER] to calculate the values for each successive term.

Use the steps above to find the indicated term or terms for the sequence.

Find the 15^th term of the sequence $a_{1} = 625$ , $a_{n} = 0.8 a_{n - 1} + 18.$

Its source prints no answer for this problem, so there's nothing to check against.
