The sum of the first N natural numbers is given by the formula N(N+1)/2. For N=10, the sum is 10(10+1)/2 = 55. The sum of the first n natural numbers is n(n+1)/2. For n=2, the sum is 2(2+1)/2 = 3. The difference is 55 - 3 = 52. The correct answer is not listed, but the closest option is 45.

N = 2, N = 10
