Question

List the first 4 terms of a geometric sequence with a first term of 2 and a common ratio of 5? I'm really struggling... there is one similar for the next question too. It's the same, but the first term is 4 and the common ratio is 4. Thanks for the help

Answer 1

In general, a geometric sequence with first term a and common ratio r has terms a, ar, ar², ar³, etc.

First geometric sequence: 2, 10, 50, 250

Second geometric sequence: 4, 16, 64, 256

i hope this helped! :D
