Did you know?
WebThe sum of n natural numbers is represented as [n(n+1)]/2. If we need to calculate the sum of squares of n consecutive natural numbers, the formula is Σn 2 = [n(n+1)(2n+1)] / 6. It is easy to apply the formula when the value of n is known. Let us prove this formula using the principle of mathematical induction. WebNumbers which follow each other in order, without gaps, from smallest to largest. 12, 13, 14 and 15 are consecutive numbers. 22, 24, 26, 28 and 30 are consecutive even …
WebBut if you add two consecutive numbers the answer is always an odd number. Gauss noticed that if he was to split the numbers into two groups 1 to 50 and 51 to 100 he could add them together vertically to get a sum of 101. We find its consecutive integers as 7 2 and 7 4 or 9 and 11. ½ n n 1 where n is the last number in the sum.
