Question

6, -18, 54, ...
what is the equation for the sequence

give the 14th term

Answer 1

-9,565,938

Explanation:

The first term of this geometric sequence is 6. Its common ratio is -3. The n-th term is given by ...

an = (6)(-3)^(n-1)

Then the 14th term is ...

a14 = 6·(-3)^(14-1)

a14 = -9,565,938
