Today I am asking you a tricky formula question. This is asked by Ionel on the Introduction to VLOOKUP, OFFSET & MATCH Formulas post.
The question is,
I have data in three columns: A,B,C and I want to get the average of the closest two values out of three in each row. Could you help me with a formula for this?
Now, how would you go about it?
What does closest of two mean?
We can assume that close-ness is nothing but distance between 2 numbers on numeric scale. So 3 is closer to 2 and 4 compared to 1 or 5.
Your challenge:
Assuming your data is in A2:C10, what formula will you write in D2:D10 to solve this?
Go ahead and get some coffee and get thinking.
Want to cop-out?
I have posted one solution in the next comment. You can see how I went about solving it.

Sweet! I won! Thank you so much, Chandoo! I'm really speechless! I'll look out for an e-mail from you. Again, I really appreciate it, and I can't wait to fire it up!
Sincerely,
Tom "this one" 🙂
Thank You... Thank You... Thank You... 🙂
Hi,
Don't want to ruin your party.. 😉 but I noticed that when you sort the list A2:B11 (step 2), the RAND function re-calculates the numbers so that they are different and in mixed order again. I had to paste the whole area as values first and then sort to get it to work.
Wonder if the same happened to you because in your list at least Greg has a higher value than Tom 🙂
