​

Answer 1

Answer:

C)5625

Explanation:

The sum of the odd integers up to 150 is obtained by subtracting the sum of the even integers up to 150 from the sum of all the integers up to 150. The sum of all of the integers up to 150 is 150*151/2 = 11325. The sum of all of the odd integers up to 150 is therefore 11325–5700=5625.
