The pattern is multiplying by 3.

The formula will be: 0.2(3)^n-1

Answer:

145.8

Step-by-step explanation:

The geometric ratio is

.6/.2 =3

The formula is given by

an = a1 r^ (n-1)

The first term is .2

an = .2 (3) ^ (n-1)

We want the 7th term

a7 = .2 * (3) ^(7-1)

     = .2 (3)^6

    = .2*729

    =145.8
