Question

What is the 10th term in this geometric sequence?
2,4, 8,16,.....​

Answer 1

1024

Explanation:

you can plug 10 to the explicit formula. f(n)= a times r to the power of n minus 1. A is the first term, r is the common ratio and n is the nth term. 2 times 2 to the power of 10 minus 1. 2 times 2 to the power of 9 is 1024. Hope this helps!
