The average is 2 - Adding all the numbers together gives a total of 42. There are 21 numbers in the range - therefore the average is 2.
The arithmetic mean is 36.
it is 33; you can add all up and divide by 17, or simply add first and last and divide by 2
The sum of the integers 1 to 99 is 4950. An easy way to figure this out is using the equation N*(N+1)/2 where N is the largest number in the set.
The sum of all integers between 45 and 90 is 3105.
The average is zero.
The average is 2 - Adding all the numbers together gives a total of 42. There are 21 numbers in the range - therefore the average is 2.
To find the average of integers, add them all together then divide the total by the number of integers.
The average is -3
The sum of all integers from 1 to 20 inclusive is 210.
There are 238 - 1 = 237 numbers between 1 and 238. To find the number of digits, we need to consider the range of numbers from 1 to 9 (1-digit numbers), 10 to 99 (2-digit numbers), and 100 to 238 (3-digit numbers). There are 9 one-digit numbers, 90 two-digit numbers, and 139 three-digit numbers between 1 and 238, totaling 9 + 90 + 139 = 238 digits.
The arithmetic mean is 36.
1 is a common factor for all integers.
it is 33; you can add all up and divide by 17, or simply add first and last and divide by 2
810. All of the integers from -30 to30 cancel each other out by adding a negative to a positive. Then all you need to do is add the integers from 31 to 50. (31 + 32 + ....+50)
The sum of the integers 1 to 99 is 4950. An easy way to figure this out is using the equation N*(N+1)/2 where N is the largest number in the set.
The sum of all integers between 45 and 90 is 3105.
