Math Problem Statement
Question 3 The numbers in the table below are the result of executing an algorithm that has one parameter N, a non-negative integer, and produces sequences of integers as outputs. For values of N from 0 to 5, the algorithm produces the following sequences of numbers as outputs:
N
output
0
1
-1 0 3
2
-4 -3 0 5 12 21
3
-9 -8 -5 0 7 16 27 40 55
4
-16 -15 -12 -7 0 9 20 33 48 65 84 105
5
-25 -24 -21 -16 -9 0 11 24 39 56 75 96 119 144 171
Determine the algorithm that was used to generate the numbers in this table, and
Write it down.
Execute it for N = 6, and write down your result.
What is the sequence of numbers for N = 6?
(Give your answer as integers separated by single spaces.)
