Answer:
5, 6, 7
Explanation:
This question deals with linear equetion.
Let the first no. x , the 2nd one x + 1 and the 3rd no. will be x + 2 .
we have given that 3 consucetive sum are 18 so we write this equetion as
x + x + 1 + x + 2 = 18
3x + 3 = 18
3x = 18 - 3
3x = 15
3x/3 = 15/3
x = 5
so the 1st no. is 5
the 2nd no. is 5 + 1 = 6
the 3rd no. is 5 + 2 = 7
and the no. is 5, 6, 7
