The sum of the whole numbers from 1 to 680 is 231540.

What is the sum of the whole numbers from 1 to 680?

Arithmetic sequence is a list of numbers where each number is equal to the previous number, plus a constant called the common difference.

The formula for sum of first n numbers can be expressed as;

Sₙ = (n/2)( a₁ + aₙ )

Where n is the number of terms, a₁ is the first term and aₙ is the nth term.

Given that,

The numbers are whole numbers from 1 to 680

  • Number of terms n = 680
  • First term a₁ = 1
  • 680th term a₆₈₀ = 680
  • Sum S₆₈₀ = ?

Plug the given values into the equation above.

Sₙ = (n/2)( a₁ + aₙ )

S₆₈₀ = (680/2)( 1 + 680 )

S₆₈₀ = 340( 681 )

S₆₈₀ = 231540

Therefore, the sum of the whole numbers from 1 to 680 is 231540.
