how to find the SUM of consecutive numbers inclusively
Find average of the numbers then multiply that by the amount of integers inbetweenex- Sum of integers from 10-50, inclusively10+50/2= 3050-10+1= 4141×30=1,230
To find the sum of consecutive numbers inclusively, you can use the formula:
sum = (n/2) x (first number + last number)
Where:
– n is the number of terms in the sequence
– the first and last numbers are the first and last terms in the sequence
For example, if you want to find the sum of the numbers from 1 to 10 inclusive, n is 10, the first number is 1 and the last number is 10. So, using the formula:
sum = (10/2) x (1 + 10) = 5 x 11 = 55
Therefore, the sum of the consecutive numbers from 1 to 10 inclusive is 55.
