$65\8 66\8 67\8$


​

Answer 1

Answer:

Common Difference of the A.P. 65/8. 66/8, 67/8 is 1/8

That is, D = 1/8

Step-by-step explanation:

A.P. = 65/8 , 66/8 , 67/8

So, A = 65/8,  N = 3 terms, L = 67/8 and D = ?

L = A + (N-1)D

67/8 = 65/8 + (3-1)D

67/8 - 65/8 = 2D

67-65/8 = 2D

2/8 = 2D

D = 2/8*2

D = 2/16

D = 1/8
