What are the first 4 terms of a geometric sequence with the first term of 4 and a common ratio of 4?

First term • ratio^0 ;4•4^0=4•1= 4

Second term • ratio^1 ;4•4^1=4•4=16

Third term • ratio^2. ;4•4^2=4•16=64

Fourth term •ratio^3. ;4•4^3=4•64=256

So the four terms are 4, 16, 64, 256

Okay i already have it though
