Ans : Missing number is 30
As per Arthimetic Sequence formula
Sn=n/2{2a1+(n-1)d}
Where,
a1=1(first term)
d=1 (common difference)
n=46 (No of terms)

S46=1081
S47=1128
Sumit answer is between S46 & S47
So Difference between
Sumit answer and S47 value
1128-1098=30
Then
S46=1081
...........-30
..........+47

....... 1098

"You want my number, do you?" said the driver. "Well, work it out for yourself. If you divide my number by 2,3,4,5 or 6 you will find there is always 1 over; but if you divide it by 11 there ain't no remainder. What's more, there is no other driver with a lower number who can say the same."
