Having trouble using the index feature on Mathcad 15 5

[Silvestre_]

I'm having the following issue on Mathcad, I want to create an iterative index to calculate the values on the table, but can't, any idea on how to solve this?

 

[IRstuff]

It doesn't like your evaluation of n, so delete the equal sign at the end of the assignment


TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

thanks, I tried but still nothing

 

[structSU10]

you need to put a place holder for the column like l[n,k

Should work if you follow IRstuff. Just type n:=1..15 without following '='

 

[yakpol]

Statement n:=1..15= converts range 'n' variable into an array, which cannot be used for indexing. See examples of PTC. Mathcad 15 is not different in this respect:

I don't know how to mention users, but thanks @yakpol and @IRstuff, i initially thought that @IRstuff was referring to the equal sign at the end of second assignment, thanks also @yakpol for your lengthy explanation, thanks also @structSU10
