Give me 5 minutes. I can answer this.

Ok, look the formula for a question like this is 

|dw:1417841024259:dw|

dtan5457 · Answer

SO your interval is 0,3. You plug 0 and 3 into the original equation.

|dw:1417841147178:dw|

so the avg would be 27.

I used that formula..so..

dtan5457 · Answer

Actually, only mistake I see I did is that it's suppose to be 

78-0 divided by 3.

the avg is 26, I forgot to subtract x for F o 3.
