Answer:

 The convergence of the sequence is found to be \frac{4}{7}

Step-by-step explanation:

As the nth term T_{n}=\frac{1}{(3n-2)(3n+1)(3n+4)}

We get a partial fraction via,

T_{n}=\frac{1}{6} [\frac{1}{(3n-2)(3n+1)} -\frac{1}{(3n+1)(3n+4)} ]

T_{1}=\frac{1}{6}[\frac{1}{1.4}-\frac{1}{4.7} ]

T_{2}=\frac{1}{6}[\frac{1}{4.7}-\frac{1}{7.1} ]

Then, Sn=∑Tn=\frac{1}{6} [\frac{1}{1.4} -\frac{1}{(3n+1)(3n+4)} ]

=\frac{1}{24}-\frac{1}{6(3n+1)(3n+4)}

As n⇒∞

S_{n}=\frac{1}{24}-0\\=\frac{1}{24}

As a conclusion, the sequence's 100th term is equal to ( \frac{4}{7} ) 0f 99 times the first term, or 1/4.7.10. The convergence of the series is matched by the simplification of this to  \frac{4}{7} . The sequence conforms to \frac{4}{7} as a result.​
