The $7^{th}$ term of an $A.P.$ is $108$ and the $11^{th}$ term is $212$. Then,its $n^{th}$ term is $\ldots \ldots \ldots \ldots$

In an $AP$,if $a = 3.5, d = 0, n = 101$,then $a_{n}$ will be

The first term of a finite $A.P.$ is $5$ and its last term is $95$. If the common difference of the $A.P.$ is $5$,then there are $\ldots \ldots \ldots$ terms in the $A.P.$

Find the $45^{th}$ term of the $A.P.$ $13, 8, 3, -2, \ldots$

For an $A.P.$,the sum of the $4^{th}$ term and the $8^{th}$ term is $24$,while the sum of the $6^{th}$ term and the $10^{th}$ term is $34$. Find the first term $a$ and the common difference $d$ of the $A.P.$

Fill in the blanks in the following table,given that $a$ is the first term,$d$ is the common difference,and $a_{n}$ is the $n^{th}$ term of the $AP$:

$S.No.$	$a$	$d$	$n$	$a_{n}$
$(i)$	$7$	$3$	$8$	$...$
$(ii)$	$-18$	$...$	$10$	$0$
$(iii)$	$...$	$-3$	$18$	$-5$
$(iv)$	$-18.9$	$2.5$	$...$	$3.6$
$(v)$	$3.5$	$0$	$105$	$...$
