ANSWER
Sum of the digits at the odd places = 8 + missing number + 2 = missing number + 10
Sum of the digits at the even places = 6 + 7 = 13
Difference = [missing number + 10 ] – 13 = Missing number – 3
According to the rule, missing number – 3 = 0 [Because the missing number is a single digit]
Thus, missing number = 3
Hence, the smallest required number is 3.
x=3
