Find the 7th term of this geometric sequence 0.2, 0.6, 1.8,

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

The pattern is multiplying by 3.

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

So, 0.2 (3) ^6=145.8
