Question

What is the sum of all the odd integers between 8 and 26​

Answer 1

Explanation:

Between 8 and 26, there are: (25 - 9)/2 + 1= 9 (odd numbers)

The sum of each pair of odd numbers: 25 + 9 = 34

The sum of all odd numbers: 34x9/2 = 17x 9 = 153

hope it helps but am not sure

Answer 2

The sum of the first "N" positive odd integers = N^2

There are 13 odd imtegers between 1 and 26, inclusive.....and there are 4 odd integers between 1 and 8, inclusive

So....the sum of the odd integers between 8 and 26 equals the difference in the above, and we have....

13^2 - 4^2 = 169 - 16 = 153
