Answer by MRperkins(300)   (Show Source):
You can put this solution on YOUR website! to find the mean, you add all the numbers and divide by the amount of numbers, so  we are told that this is equal to 11.25
.
so 
solve for N. Then find your second number (N+2) and multiply N and N+2 to find the product and your answer to the question.
.
Do you want your math questions answered quickly and completely? Do you want to ask follow up questions like, “How do you do that?” or “Why did you do that?”? Email your questions to justin.sheppard.tech@hotmail.com and I will answer your questions within 12 hours of submission (usually within 2-3 hours of submission). I charge $2 per question and I will provide a .pdf file of the problem worked out. I will also offer to discuss the problem with you over the phone, through skype, or via an online whiteboard. Payments to be made securely through PayPal AFTER you are satisfied with the answer and services that I provide. This eliminates the possibility of being scammed (worst case scenario is that I provide you with your answer and you don’t pay me).

Respectfully,
