Hi everyone, I have one table with 2 columns: X values and Y values But I have something like 20 or 30 rows. i need to find the approximative value Y for a given X but my input X is always between two values of X in my table For example: X - Y 1 - 10 2 - 20 3 - 30 For X=2.5, Y = ? This is a bit more complicated because I have a linear function between each rows. I have to use LINEST() and INTERCEPT() for values X(2:3) Y(20:30) when I give the input X=2.5 I have to use LINEST() and INTERCEPT() for values X(1:2) Y(10:20) when I give the input X=1.5
I can write a formula saying, IF my data input is above 2 and below 3, select this and this, IF my data.... But for such a long table, I will have too many if Do you know if it's easy to target the above and below cell according to my data input? Thanks -- Are you =EXP(E:RT) or =NOT(EXP(E:RT)) in Excel? And do you wanna be? It’s =TIME(2,DO:IT,N:OW) ! Join official Facebook page of this forum @ https://www.facebook.com/discussexcel FORUM RULES 1) Use concise, accurate thread titles.
