Answer 12

To quickly find the sum of a set of consecutive numbers, you can add the first and the last and multiply by half the number of values in the list. Based on that, we get the equation:

(1 + x)(x/2) = 496 where x is the day of the award.
x2 + x = 992 distribute and multiply both sides by 2
x2 + x - 992 = 0
(x + 32)(x - 31) = 0 factor and apply the zero product rule
x = -32, 31 can't have negative days
x = 31
