Answer: the  integers are 4,5and 6

Step-by-step explanation: lets say the integers are: x,x+1,x+2

consecutive integers are numbers that follow each other like:1,2,3 or 2,3,4 in that sequence.

since the sum of the integers has been given to be 15 we add our equation: x+x+1+x+2=15

  • add the like termsx+x+x+1+2=15
  • 3x+3=15
  • 3x=15-3=12
  • 3x=12
  • divide on both sides by 3 to get
  • x=4
  • lets substitute our answer to our equation
  • if x=4
  • x+1=4+1=5
  • x+2=4+2=6
  • therefore the integers are:4,5 and6
