What is the sum of the numbers 21 to100?
Without just going and doing the addition, you can use this formula:Sum of 1 to N is: (N+1)*N/2. So take sum of [1 to 100], then subtract off the sum of [1 to 20], and you'll have left the sum [21 to 100].Sum [1-100] = (100+1)*100/2 = 5050. Sum[1-20] = (20+1)*20/2 = 210.So 5050 - 210 = 4840
