Q. Find wrong number in 326, 166, 86, 56, 26, 16.
Answer: 56 is the wrong one.
correct number: '46'
Proof of the Answer:
It is the incorrect one as there is a pattern:
the 'ones' unit number is constant in all numbers which is '6'.
the 'tens' unit number is multiplied by 2.
For example,
'1' in 16 is multiplied by 2 to make '2' in 26 and '8' in 86 is multiplied to make '16' in 166 and 16 x 2 = 32 of '326'
This proves that '56' is the wrong number.
