Answer:
- an = 160·0.85^(n-1)
- $51.29
Step-by-step explanation:
In the given formula, a1 refers to the first term of the sequence (160), and r refers to the common ratio (136/160 = 0.85). Putting these values into the formula gives ...
a) Explicit formula: an = 160·0.85^(n-1)
__
b) The 8th term is found by putting n=8 into the formula and doing the arithmetic:
a8 = 160·0.85^(8-1) ≈ 51.29
After 8 months, the price is predicted to be $51.29.
