Question

Please tell general formula of 1/4, 1/8, 1/16, 1/32. Please explain also.....

Answer 1

Answer:

a=1/4

b=1/8-1/4=1-2/8=-1/8

General term is given by

$an = a + (n - 1)d \\ an = \frac{1}{4} + (n - 1) \frac{ - 1}{8} \\ = \frac{1}{4} + (\frac{ - 1}{8} n) + \frac{1}{8}$

General term is the nth term
