Text Solution

Verified by Experts

The correct Answer is:
B
The given number series is as follows:

Pairs of successive numbers with a difference of 2,

i.e. `(6, 4), (4,2), (5,3), (8, 6), (1,3), (8,6) i.e. (6 - 4) = 2, (4 - 2) = 2, (5 – 3) = 2, (8 – 6) = 2, (1 - 3)= 2, (8-6)= 2`
Therefore, total number of such pairs = Six.
