Question

1+2+3+...+101= Срочно!!!

Answer 1

101*(1+101)/2=51*101=5151

Answer 2

The sum of the numbers from 1 to 101 can be calculated using the formula for the sum of an arithmetic series:

Sum = (n/2) * (first term + last term)

In this case, the first term is 1, the last term is 101, and there are 101 terms in total.

Sum = (101/2) * (1 + 101) Sum = 50.5 * 102 Sum = 5151

Therefore, the sum of the numbers from 1 to 101 is 5151.
