Answer:
Step-by-step explanation:
f(x) = -8x + 20
f(-1) = -8* -1 + 20 = 8+20 =28
5 - 2[f(-1)] = 5 - 2*28 = 5 - 56 = -51
Seems to be a geometric sequence which is found by

an=nth term
a1=first term
r=common ratio
first term is 0.75
it doubles each time so common ratio is 2

to find the nth term, input n and evaluate
example
to find the 20th term




just to find the kth term, input k for n in
