## What is the sum of first 100 odd numbers?

The number series 1, 3, 5, 7, 9, . . . . , 199. Therefore, 10000 is the sum of first 100 odd numbers.

## What happens if you add consecutive odd numbers?

The sum of any set of consecutive odd numbers starting with 1 is always equal to the square of the number of digits that were added together. Sum of first two odd numbers = 1 + 3 = 4 (= 2 x 2). Sum of first three odd numbers = 1 + 3 + 5 = 9 (= 3 x 3).

**What is the sum of the first 1000 odd numbers?**

The first 1000 consecutive odd numbers run from 1 to 1999. The first 1000 consecutive even numbers run from 2 to 2000. Each even number is an odd number plus one. So then the total sum is the sum of all the odds twice plus 1000. where OS is odds summed from 1 to 1999 and ES is the evens summed from 2 to 2000.
