What sums equal x2?

Anonymous

∙ 13y ago

Updated: 4/28/2022

The sum of the first x odd numbers is equal to x2 (for integers only.)

For example, take 72: We'll take the first seven odd numbers:

1 + 3 + 5 + 7 + 9 + 11 + 13

= 4 + 12 + 20 + 13

= 16 + 33

= 49

This then, can be expressed as follows:

x

x2 = Σ(2n - 1)

n=1

Which is the only number which is equal to the sum of its digits?

Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.
