Question

Given the sequence: {2, 12, 72, 432, 2592…}, a12 = ???

Answer 1

can you see the pattern here?
how do we get from 2 to 12, and then 12 to 72 by the same operation?

Answer 2

Hint - you multiply by some number

Answer 3

2 * something = 12
12 * same number = 72

Answer 4

yes

and 72 * 6 = 432 and so on

Answer 5

you can write the sequence as

a, ar, ar^2, ar^3

where a = 2 and r = common ratio = 6


so 12th term a12 = ar^11 = 2* 6^11

Answer 6

yes u r right
