I'm trying to trend out some numbers. I have two sets of numbers: The first we can call a "local" projection and the second we can call a "national" projection.

For the national projection I know all 3 numbers: Low, Medium, High
For the local projection I know only 1 number: Low

I would like to use the TREND/FORECAST function to predict what the Medium and High numbers are for Local. Is this possible? Also not sure if it matters, but the High number is the more important one to know because if I know that, I can interpolate the Medium as the 50th percentile between the Low and High.

The table below depicts what I'm trying to do with the 'X's representing what I need to use the TREND/FORECAST function to predict.

Any help would be much appreciated!

Does the VLOOKUP table have to be sorted?
No! when you are using an exact match, the VLOOKUP table can be in any order. Best-selling items at the top is actually the best.

Hi wring,

why would you need a TREND or forecast formula... In your example I would simply use: E2: =A2/B2*C2 and F2: =A2/B2*D2

Ciao,
