Como say: --
1 + 3 + 5 + 7 + 9 = 25

Puzzling say: Here's a quick shortcut.

The sum of the first N consecutive positive odd integers is always N².

You can see that below:
1 = 1 <-- 1²
1 + 3 = 4 <-- 2²
1 + 3 + 5 = 9 <-- 3²
1 + 3 + 5 + 7 = 16 <-- 4²

Answer:
1 + 3 + 5 + 7 + 9 = 25 <-- 5²

Now impress your teacher by figuring out that the sum of the first 100 consecutive positive odd integers is 10,000 :)

JonZ say: Simple, the first five, consecutive, positive odd numbers are: 1, 3, 5, 7 & 9. Add them together and you get 25.

Captain Matticus, LandPiratesInc say: 1 + 3 + 5 + 7 + 9 = 25

The sum of the first n consecutive odd integers is n^2
