~~ i could use some (its multiple choice and i put more points)~~

what are the first three terms of the sequence
a1=1 and an=4(an-1)^3 ?

a) 1,256,500
b) 1,4,256
c) 4,8,256
d) 4,32,108

B) 1, 4, 256

Step-by-step explanation:

a1 = 1

an = 4(an-1)^3

a2 = 4(a2-1)^3

a2 = 4(a1)^3

a2 = 4(1)^3

a2 = 4

a3 = 4(a2)^3

a3 = 4(4)^3

a3 = 4(64)

a3 = 256

B) 1, 4, 256
