Question

write the first two terms of the sequences:- tn=1/n2-1​

Answer 1

Answer:

$First \:term \: is \: not \: defined .$

$Second \:term = \frac{1}{3}$

Step-by-step explanation:

$Given \: t_{n} = \frac{1}{n^{2} - 1 }$

$First \: term = t_{1} = \frac{1}{1^{2} - 1 } \\= \frac{1}{1-1}\\= \frac{1}{0} \\= Undefined$

$Second \: term = t_{2} = \frac{1}{2^{2} - 1 } \\=\frac{1}{4-1}\\= \frac{1}{3}$

Therefore.,

$First \:term \: is \: not \: defined .$

$Second \:term = \frac{1}{3}$
