I have an interesting issue I am about to take on. I need to calculate a partial sum.
Y = T - a + Σ x/(1+b)^i
Where the partial sum (Σ) is from i=1 to n and varies for each record between 1 and 25. Basically all of the terms of the equation are known and are in a single row of a table except for y. Each record has this single row of known terms.
I would like to add a column to the table for y using the data from that single row into this equation.
How do I get this partial sum to resolve? Is a For loop in the script my best option?
