**Reiny**, Thursday, January 20, 2011 at 8:47amnumber of males --- x

number of females --- 3x-5

Can you form the equation from here and solve it?

**Reiny**, Thursday, January 20, 2011 at 8:52amPlease do not post a new question as a reply to somebody else's problem.

Tutors might think it has been answered and not look at it.

I will set it up for you...

1st integer ---- x

2nd integer ----x+1

3rd integer ----x + 2

"smallest plus largest equals twice the middle"

x + (x+2) = 2(x+1)

solve....

ahhh, glancing at this equation it is obvious that you will get

0=0

that means that it will be true for all consecutive even integers.

e.g. let's try 4,5,6

is 4+6 = 2(5) ? YES
