List-Calculation - sumSeq
Function: Determines the lowest-degree polynomial that generates the sum of the first
n
terms of your sequence. If we evaluate the resulting polynomial at 1, for
example, the result will be the first value in your list. If we evaluate the resulting
polynomial at 2, the result will be the sum of the first two values in your list.
When two columns of values or two lists are specified, the resulting polynomial
returns a sum based on a sequence.
Syntax: sumSeq(start cell:end cell[,start cell:end cell][,variable])
Example: To determine a polynomial that generates the sum of the first
n
terms for the
sequence expressed by the values in cells B1 through B4 with a variable of “
y
”,
and input the result in cell A1:
