Respuesta :

10-05-2018

x= 1st integer
x+1= 2nd integer
x+2= 3rd integer
x+3= 4th integer
x+4= 5th integer

Add the integers

x + (x+1) + (x+2) + (x+3) + (x+4)= 25
combine like terms

5x + 10= 25
subtract 10 from both sides

5x= 15
divide both sides by 5

x= 3

x+2= 5 third integer

ANSWER: The 3rd integer is 5.

Hope this helps! :)
