26 is nearly half of 55. 8 and 10 are consecutive even numbers as are 24 and 26. Once youve plugged in the integer multiply the integer by itself plus 1 2 or 4 depending on your formula.
To represent consecutive numbers algebraically let one of the numbers be x.
Write it out as an equation and it should look like. The sum of the numbers 9-40 equals 784. If the first number is assigned the letter n then the second number that is consecutive must be and the third number must be. By using Carl Gausss clever formula n 2 first number last number sum where n is the number of integers we learned how to add consecutive.
