What is the 100th triangular number?

krek1111 [17]

Answer:

$T_1_0_0=5050$

Step-by-step explanation:

A triangular number is number that can be recomposed in the form of an equilateral triangle. Each triangular number is defined by:

$T_n=\frac{n^2+n}{2} \hspace{5} n\in N$

Hence, evaluating n=100

$T_1_0_0=\frac{(100)^{2}+100 }{2} =5050$
