GIVEN

• First 7 multiples of 8
• First 8 multiples of 7

TO FIND

The average of the given terms

SOLUTION

We can simply solve the above problem as follows;

We know that,

Average = Sum of all observation/Total number of observation.

First 7 multiples of 8 = 16,24,32,40,48,56,64,72

$Average \: = \frac{ 8+ 16 + 24 + 32 + 40 + 48 + 56 }{7}$

= 224/7

= 32

First 8 multiples of 7 = 7,14,21,28,35,42,49,56

$Average = \frac{7 + 14 + 21 + 28 + 35 + 42 + 49 + 56}{8}$

= 252/8

= 31.5

Hence, The average of First 7 multiples of 8 is 32 and the average of First 8 multiples of 7 is 31.5.
