Answer:

[tex]T_1_0_0=5050[/tex]

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:

[tex]T_n=\frac{n^2+n}{2} \hspace{5} n\in N[/tex]

Hence, evaluating n=100

[tex]T_1_0_0=\frac{(100)^{2}+100 }{2} =5050[/tex]
