Q: What is the sum of the first 20 positive integers?

Write your answer...

The sum of the first 20 integers is 190.

The sum of the first four non-negative, consecutive, even integers is 20.

The sum of all integers from 1 to 20 inclusive is 210.

There are 20.

Two of them. Two of them. Two of them. Two of them.

Many people would consider 0 to be the first even positive integer, however similar to the neutron in an atom, 0 holds a neutral position. Meaning it is neither a proton (+1) or electron (-1). So our first positive even integer would be 2.2 + 4 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 110, which is the sum of the first ten evenly positive integers.

The integers are 18 and 20.

The integers 2 and 10 have a product of 20 and a sum of 12.

20,21 and 22 are three consecutive integers whose sum is 63. 20+21+22

The integers are 19, 20 and 21.

20+6

The numbers are -22, -21 and -20.

The integers are 20 and 22.

19, 20, and 21

20 and 21

18, 19, 20

You can list them out and add them up: 3 + 13 + ... + 193 {20 items}, or you can recognize the sequence: (n = 0..19) of (n*10 + 3), the sum would be 20*3 + 10*Sum[(n=0..19) of just n], which is 20*3 + 10*[190] = 60 + 1900 = 1960. If you add up the column of numbers, you get the same result.

The product of two negative integers is positive as for example -4 times -5 = 20

The two even integers are 20 and 22. 20 + 22 = 42.

First integer divisible by 10 is 10 itself .So the numbers are 10,20,30,40 and so onthe sum is10+20+30+40+....+990+100010(1+2+3+4+.....+99+100)10*100*101/250500

Negative 2 - negative is 18 integers. Positive 18 to negative is 20 integers.

16+18+20= 54

25

18 + 20 = 38
