Question

Write the rule for the following geometric sequence: 1, 1/2, 1/4, 1/8,...

Answer 1

Multiply 0.5 (or 1/2) each time

1 x 1/2  = 1/2
1/2 x 1/2 = 1/4
1/4 x 1/2 = 1/8
etc.

hope this helps

Each fraction is half of the previous fraction
Each denominator is double than the previous denominator(nominator always 1)
1/8,1/16.1/32,1/64
