There are an infinite number of triangular numbers that are also squares. You can generate such numbers using the formula:
Sn+1 = 4Sn(8Sn + 1)
With the first Sn being 1.
This gives the next such number as:
Sn+1= 4 (8 + 1)
= 36
You can then plug that into the equation to get:
Sn+1 = 4 x 36 (8 x 36 + 1)
= 41616
and so on.
1 and 36
The sum of the first n cubed numbers is the square of the nth triangular number.
Square numbers.
Yes. 1 is both square and triangular.
Yes. 36 is a triangular number, because it is 1+2+3+4+5+6+7+8, and it is also a square number, because 36=6x6. 1 is another square number that is traditionally considered to be triangular.

There are an many triangular numbers that are also square numbers. Simply put, the sum of two consecutive triangular number equals a square number. Examples include 1 and 36.
No - but it is a square number. 1,3,6,10,15,21 & 28 are all triangular numbers. 1,4,9,16,25 & 36 are all square numbers.
34
The sum of the first n cubed numbers is the square of the nth triangular number.
if you don't count 0 or 1, I believe it's 36 and 1225.
Square numbers.
Yes. 1 is both square and triangular.
Yes. 36 is a triangular number, because it is 1+2+3+4+5+6+7+8, and it is also a square number, because 36=6x6. 1 is another square number that is traditionally considered to be triangular.
One relationship is that the sum of the nth and the previous triangular numbers is equal to the nth square number.That isT(n-1) + T(n) = S(n)where T(n) is the nth triangular number and S(n) is the nth square number.
they are both types of pyramidsThey're both triangular pyramids, and all of them have a base, multiple faces, and at one end the faces come to a point.* * * * *They are NOT both triangular pyramids!
