Find the sum of odd integers from 1 to 2001.

given is an AP whose first term is 1 and d is 2

To find: the sum of odd integers from 1 to 2001


Now for the finding number of terms, the formula is




n = 1001


we know that the sum of AP is given by the formula:



substituting the values in the above equation



s = 1002001
