What is the Nth term to this sequence: 2.7, 5.4, 10.8, 21.6, 43.2

So the first term is 2.7

the second term is 5 ... 4

the thrid term is 10.8

it seems to be doubleing

so the nth term

1th term=2.7

2th term=5.4

we know there must be a power of 2 in there that is influenced by which term it is so

2^n and something more

trial and error

so (1.35) (2^n))

the nth term is (1.35) times (2^n) or 1.35 (2^n)
