SUM OF EVEN NUMBERS:
Formula: N(N+1)
How to Find N = (First Even + Last Even)/2 - 1
Example: 2+4+6+ ....... 100
N = (2+100)/2 - 1 = 50
Sum of first 50 positive even integers = (50)(51) = 2550
SUM OF ODD NUMBERS:
If N = number of odd terms then sum = (N)^2
Example: first 6 odd numbers 1,3,5,7,9,11
6 digits so (6)^2=36
