Question

Find the sum of the first 5000 odd numbers.

Answer 1

Answer:

25 000 000

Step-by-step explanation:

The sum of the first $n$ odd numbers is $n^{2}$

For example,

when $n=1$ ⇒ $1 = 1^2$

when $n = 2$ ⇒ $1 + 3 = 4 = 2^2$

when $n = 3$ ⇒ $1 + 3 + 5 = 9 = 3^2$

So the sum of the first 5000 odd numbers is $5000^{2} =25\ 000\ 000$

Answer 2

The sum of the first 5000 odd numbers is 25,000,000.
