You have not mentioned any number.
sO I shall give an algebraic ans
let lowest number be
n
largest is n+99

so average = (2n+99)/2
sum = (2n+99)/2*100 = 50(2n+99)

any number of above form and lowest of the set of numbers is n

sum of the first consecutive 100 numbers:

sum=100/2(2*a+(100-1)*1))=50(2*a+99)=100*a+4950

where a is the first term of the series

so your condition would be to subtract 4950 from the given integer and see if it is a multiple of 100

Any integer in the set beginning with 5050 and indexed by 100. The general expression for the nth sum of m consecutive numbers is:

N=m*(m+2n-1)/2

Curiously (to me) the function generates sets of series beginning with the mth triangular and indexed by m.
