Three terms of an arithmetic sequence are shown below. which recursive formula defines the sequence?
f(1) = 6, f(4) = 12, f(7) = 18

a) f (n + 1) = f(n) + 6
b) f (n + 1) = 2f(n)
c) f (n + 1) = f(n) + 2
d) (n + 1) = 1.5f(n)

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

really your just stupid if you don't know this
