What are the next two numbers in the sequence 4 16 32?

Answer 1

4, 16, 32, 128, 512

4 x 4(1-1) = 4 x 1 = 4

4 x 4(2-1) = 4 x 4 = 16

4 x 4(3-1) = 4 x 8 = 32

4 x 4(4-1) = 4 x 32 = 128

4 x 4(5-1) = 4 x 128 = 512

Nth term=a x r(n-1), where a is first term and r is common ratio between two terms.
