HEYA.!!!
8 1/8 =65/8 -a
8 2/8 =66/8 - a2
8 3/8 =67/8 -a3
Common difference = a2 -a1
=>66/8-65/8
=>1/8
d=1/8
hope it helps you :)

Answer:
The common difference is 1/8.
Step-by-step explanation:
AP is an arithmetic progression. An arithmetic progression is a sequence where the series increases or decreases in a equal order. The progression takes place such that each number is added or subtracted with the same number as number before giving a common difference.
an = a + ( n - 1 ) * d
Here we need to find the common difference d.
By rearranging the equation we get,
( an - a ) / ( n - 1 ) = d
Let us take the second term to find the common difference,
n = 2 , a = 1/8 , a2 = 2/8
( 2/8 - 1/8 ) / ( 2 - 1 ) = d
( 1/8 ) / 1 = d
d = 1/8
