Given the following sequence: 1,4,16,64,256,... Write an explicit formula of the geometric sequence.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

entering that problem on the tube might get you an answer

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
