Select the correct answer. Select the function that defines the given sequence.
–8, -20, -50, –125, 626,...

a. f(1) = 8

f(n) = -f(n − 1), for n = 2, 3, 4, ...

b. (1) = -8
f(n) = f(n − 1), for n = 2, 3, 4, ...

c. f(n) = -8. (?)" – 1)

d. f(n) = -8 (-)n = 1)

answer: haha (: i’ll go see what it is

step-by-step explanation:

σк тнє αиѕωєя ιѕ (α.)

нσρє ι ¢συℓ∂ нєℓρ υ

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
