Question

If average of 7 consecutive natural number is 97 find the largest number

Answer 1

########Hi kiddo#####

Avg = total/ no. Of things.

Let X X+1 X+2 X+3 x+4 X +5 and X +6 be the 7 numbers .

Sum = (X) +( X +1) + (X +2) +( X +3) + (X +4 )+ (X +5) +( X +6 )

= 7 X + 21

Given 7 X +21 / 7 = 97

Then, 7X + 21 = 97* 7

That is ,

7X +21= 679

7X = 679-21

7X = 658

X = 658/7

= 94

Here the largest no . Was X + 6

So substitute value if X in X+6

Therefore largest number equals,

X+6 = 94+6 =
