The sum of the first 100 odd numbers (1 through 199) is 10000 (ten thou)
It is 100^2=10000
The answer is one million (the average of the first n odd numbers is always n.)
The average is 10. You will find that the average when adding together the first n odd numbers is always equal to n.
Their sum is 10000.
The 12th odd number.
The nearest number whose square ≤ 10000 is 100. Then the greatest odd number less that 100 is 99 so there are 50 odd numbers in the range 1- 99 inclusive whose squares are less than 10000.
200*50=10000
4999 (not counting 1).
