Represent the geometric series using the explicit formula.

3, -6, 12, -24,

a.) f(n) = 3 • (2)^(n-1)
b.) f(n) = 3 • (-2)^(n-1)
c.) f(n) = f(n - 1) • (2)
d.) f(n) = f(n - 1) • (-2)

answer: ♡♡♡♡♡♡♡♡♡♡

step-by-step explanation:

sure i'm up for it

step-by-step explanation:

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
