Question

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

Answer 1

Step-by-step 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

Answer:

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
