The integers are
x
x+1
x+2
x+3
x+(x+1)+(x+2)=(x+3)+30
OpenStudy (mertsj):
Can you solve that?
OpenStudy (anonymous):
is the beginning all added togather or is any of it multiplied?
OpenStudy (mertsj):
All added together.
myininaya (myininaya):
it says sum
so that means we add (not multiply)

did you get it?
OpenStudy (anonymous):
ya I got 10/3?
OpenStudy (mertsj):
But that is not an integer.
OpenStudy (anonymous):
?
myininaya (myininaya):
\[x+x+x+1+2=x+3+30\]
\[3x+3=x+33\]
try solving it from here

you are looking for the largest intger in your problem
OpenStudy (anonymous):
yes soo do I plug the 15 into the original equation?
myininaya (myininaya):
remember we had
x <-smallest
x+1
x+2
x+3 <- largest
myininaya (myininaya):
so if x=15
then x+3= what?
OpenStudy (anonymous):
18?
