Answer:
a. 25
Step-by-step explanation:
Sₙ = n/2 * (2 * a₁ + (n-1) * d)
Sₙ = 500 a₁ = -4 d = 2
500 = n/2 * (-8 + (n-1) * 2) = n/2 * (-8 + 2n - 2) = n/2 * (2n - 10) = n² -5n
n² - 5n -500 = 0
(n - 25) (n + 20) = 0
n > 0
n = 25
7 7/8 inches
Example:
Start with a 3 inch plant
3 - 1 5/8 = 1 3/8
It grows 9 1/4 but you started at threelsdjf;lasjdflkjsdfl
9 1/4 - 1 3/8 = 7 7/8
