Question

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!

Answer 1

multiply the number with 4

Explanation:

2 8 32 128

2x4 =8

8×4=32

32×4=128

128×4=512

Answer 2

`\text{First term,}~ a =2\\\\\text{Common ratio,}~ r = \frac{8}2 = 4\\\\\text{Nth term} = ar^(n-1)\\\\\text{7th term} = 2 \cdot 4^(7-1) = 2 \cdot 4^6=8192\\ \\\text{Hence, the 7th term in the geometric series is 8192.}`
