sumSeq
Function: Finds the lowest-degree polynomial that represents the sequence expressed by
the input list and returns the sum of the polynomial. When there are two lists,
this command returns a polynomial that maps each element in the first list to its
corresponding element in the second list, and returns the sum of the
polynomial.
Syntax: sumSeq (List-1[, List-2] [,variable] [ ) ]
• “
x
” is the default when you omit “[, variable]”.
Example: To determine the sum of a polynomial for a sequence expressed by the list
{3, 5, 7, 9}
