How do you find the average of multiples of 7?
Detailed Solution
- Formula: Average = Sum of all observations/Total numbers of all observations. Average of any AP = [First term + last term]/2.
- Calculation: Sum of first 20 multiples of 7 = [(First term + Last term)/2] × Number of terms. First term = 7 and last term = 20 × 7 = 140.
- Short Trick: Average = (7 + 140)/2 = 73.5.
What is the average of the first 20 multiples of 7?
73.5
Now, to find the average we divide sum by total number of terms i.e. 20. Hence, the average of the first 20 multiples of 7 is 73.5.
How do you find the average of multiples?
How to Calculate Average. The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6 .

Is there a formula to find the average of 35 multiples?
Average is always the middle value in case of consecutive or AP series. There are 35 numbers. So the middle number will be 18th number. Therefore answer=18×7=126. If you are asking about first 35 then yes there is a formula…. Since in order to get first 35 multiples we have to multiply each number from 1–35 with 7 that is: 1*7+2*7+3*7+….+34*7+35*7
