Lesson summary Using Carl Gauss’ clever formula (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add numbers in rapid succession. We now know that the sum of pairs of consecutive numbers starting with the first and last number is equal. 2
How do you write consecutive numbers?
Numbers that are sequential from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6 etc. are sequential numbers.
What are the 5 consecutive integers that add up to 100?
Hence the numbers are 18, 19, 20, 21 and 22 which add up to 100.
What three consecutive numbers add up to 72?
. Consider the three consecutive numbers x,x+1,x+2 . The numbers are: 23, 24 and 25 and the smallest is 23.
