Rule for triangular number sequence
WebbThus, the sums 1 + 3 + 5 + 7 = 16 and 1 + 3 + 5 + 7 + 9 = 25 are both squares. Since we add the square 9 to the first sum in order to get the second, we have 16 + 9 = 25 as a sum of two squares adding to a third square. Leonardo explains that we could use any odd square in place of 9 to do the same thing. Webb1 aug. 2024 · The first 10 triangular numbers. Let’s compare this list with the first 10 square numbers: The first 10 square numbers. (An interesting observation is that 36 is both a triangular number and a square number, and appears in both lists.) We can see that the square number 9 equals the sum of triangular numbers 3 and 6.
