Answer:

Step-by-step explanation:

First 17 multiples of 7

Multiple of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105, 112, 119

Total number = 17

Average of number = Sum of all number divide by total number

Sum = 7+14+21+28+35+42+49+56+63+70+77+84+91+98+105+112+119

        = 1071

$\text{ Average of numbers }=\dfrac{1071}{17}$

                                                   = 63

Hence, The average of number of multiple of 7 upto 17 is 63
