Question

plz tellme how to find the average of first four multiple of 7​

Answer 1

Answer:

17.5

Step-by-step explanation:

Average = Sum of observations / No. of observations ...(i)

You need to find average of first four multiples of 7.

These are: 7, 14, 21 and 28

Find the sum of these numbers: 7+14+21+28 = 70

You have 4 observations. So No. of observations = 4

Using (i), we get:

=> Average = 70/4 = 17.5

Answer 2

The first 4 multiples of 7 are 7,14,21,28

To find average -sum of the numbers divided by total number of numbers

I.e 7+14+21+28/4=70/4

=17..5
