Question

If the sum of two consecutive numbers is 18 then, express the numbers using one
variable.

Answer 1

Answer:

The three consecutive numbers  are  5,  6   and  7   (5+6=11, 11+7=18) . That   implies  that   7   is   the   greatest   among   the  three

Let x, x+1 and x+2 be the three consecutive numbers

(x)+ (x+1) + (x+3) = 18

3x+3=18

3x=18−3

3x=15

x=5

thus ,

second number is x=1

i.e 6
