Question

Four consecutive numbers that add up to 74

Answer 1

Let the numbers be x, x+1,x+2,x+3

x+x+x+x+1+2+3=74

4x=74-6

4x=68

x=17

hence, numbers will be 17,18,19 and 20

Answer 2

Let the first number be x

Four consecutive numbers - x , x+1 , x+2 , x+3

sum - 74

equation - x  +  x+1  +  x+2  +  x+3 = 74

                 17  +  17+1  +  17 + 2 + 17 + 3 = 74

                 17 + 18 + 19 + 20 = 78

∴ x = 17
