Question

average of odd numbers upto 999​

Answer 1

Answer:

$\huge{\boxed{\boxed{\red{\ulcorner{\mid{ \overline{\underline{\bf{Answer:-}}}}}\mid}}}}$

Step-by-step explanation:

Sum of all integers from 1–999 is 1000 x 999/2=499500. Subtract the sum of all the even numbers. This is obviously the equivalent of double the sum of all the integers from 1–499,which is 2 x 500 x 499/2= 249500.
