Question

formula to add consecutive numbers

Answer 1

By using Carl Gauss's cleverformula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs inconsecutive numbers starting with the first and last numbers is equal.

Answer 2

n+(n+1)=n×n or n^2
ex 2+3
