(a(i))[1]
The first five terms of a sequence are: 3, 8, 13, 18, 23. Determine the next term in the sequence.
(a(ii))[2]
Find an expression for the nth term in the sequence.
(b)[3]
$T_n$ is the nth term of another sequence. The first five terms are $T_1=\frac{3}{4}$, $T_2=\frac{8}{9}$, $T_3=\frac{13}{16}$, $T_4=\frac{18}{25}$, $T_5=\frac{23}{36}$. Determine $T_{25}$.
