Question

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

Answer 1

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)
