let the first ,second and third number be x,x+1,x+2 respectively.
Multiplied by 2,3,4 respectively = 2x,3x+3,4x+8
Sum = 74
2x+3x+3+4x+8=74
9x+11=74
9x = 63
x = 7
The consecutive numbers are 7x,8(x+1) and 9(x+2)

let the required no.be x,x+1and x+2.
2*x+3(x+1)+4(x+2)=74
2x+3x+3+4x+8=74
9x +11=74
9x=74-11
9x=63
x=63/9
x=7
the required no. are 7,7+1=8,7+2=9
