I believe that it was Leonhard Euler (1707-1783), who as a schoolboy found
a neat way of doing it.
=============================
Answer #2:
I believe that was Johann Carl Friedrich Gauss. The point of that famous story
wasn't the fact that he did it, or the way he did it, but how old he was when
he did it.

The consecutive numbers that add up to 36 are 11, 12, and 13. When you add these three numbers together (11 + 12 + 13), the sum is 36.
They are called just that: "consecutive numbers".They are called just that: "consecutive numbers".They are called just that: "consecutive numbers".They are called just that: "consecutive numbers".
You can multiply any numbers together.
There are none. However there are two consecutive ODD numbers 299 and 301

The "natural numbers" are the ones you use to count . . . 1, 2, 3, 4, etc. Consecutive natural numbers are two or more of them that occur together as you count, with no holes or spaces in the group. 23, 24, and 25 are consecutive natural numbers. 63 and 64 are consecutive, but 63, 64, and 67 are not.
The two consecutive numbers that total 240 are 119 and 120. This is because if you add them together (119 + 120), the sum equals 240.

Consecutive whole numbers will have an odd sum. Consecutive odd numbers, or consecutive prime numbers, will be 29 and 31.
