Did you know if you add up all the numbers from 1 to 100 consecutively (1 + 2 + 3...) it totals 5050?
there is a formula for calculating the sum of consecutive numbers. The formula is:
n(n + 1) / 2
where n is the last number in the sequence. So, the sum of the numbers from 1 to 100 is:
100 * 101 / 2 = 5050
