Question

the sum of 9 consecutive numbers is 99 find the largest of these whole numbers​

Answer 1

Given: 9 consecutive numbers, sum is 99

To find: Largest of the 9 numbers.

Solution:

• Now we have given 9 consecutive numbers.

• Let the consecutive numbers be:

             x, x + 1, x + 2, x + 3, x + 4, x + 5, x + 6, x + 7 and x + 8

• Now adding all these 9, we get:

              x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 + x + 7 + x + 8

            9x + 36 = 99

             9x = 63

             x = 7

• So the largest number will be: x + 8

             7+8 = 15

Answer:

            So the largest of the 9 numbers is 15.

Answer 2

Answer:

X+X+1+X+2+x+3+X+4+X+5+X+6+X+7+x8

9x+36=63

X=7

X+8=7+8

15
