Find the 7th term in the sequence

0.2,0.1,0.05,0.025

Basically you just divide by 2 each time

0.2, 0.1, 0.05, 0.025, 0.0125, 0.00625, 0.003125

The 7th term is 0.003125.

Another way to solve this is making an equation

An=A1 x r^ (n-1)

Where A1 is the first term

An = the nth term in the sequence

n = the term number that you want

r = the common ratio

A7=.2x (.5) ^6=0.003125
