0.5n(n+1)I finally got the thing! Awesome!

Or alternatively:

½ n2 + ½ n

or:

½ (n2+n)

a more simple answer is

(n2 ÷ 2)+½ n

e.g:- 10x10=100

2=50+5=55

What is the nth term of 1 3 6 10 15 21?

The sequence 1, 3, 6, 10, 15, 21 consists of triangular numbers, where the nth term can be calculated using the formula ( T_n = \frac{n(n + 1)}{2} ). This formula represents the sum of the first n natural numbers. For example, for n = 1, the term is 1; for n = 2, it is 3, and so on. Thus, the nth term is the sum of the integers from 1 to n.


What is the Nth term formula for rectangular numbers?

What is the nth term for the triangular numbers 1 3 6 10 15 21?

The nth term for the triangular numbers can be expressed using the formula ( T_n = \frac{n(n + 1)}{2} ), where ( n ) is a positive integer representing the position in the sequence. This formula calculates the sum of the first ( n ) natural numbers, resulting in the sequence 1, 3, 6, 10, 15, 21, and so on. For example, for ( n = 4 ), ( T_4 = \frac{4(4 + 1)}{2} = 10 ).

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.
