In the following $APs,$ find the missing term in the box: $2, \square, 26$

The $10^{th}$ term of an $A.P.$ is $52$ and its $17^{th}$ term exceeds its $13^{th}$ term by $20$. Find the $A.P.$ and also its $30^{th}$ term.

There are $\ldots \ldots \ldots \ldots$ multiples of $3$ lying between $1$ and $50$.

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 $A.P.$

Choose the correct choice in the following and justify: $30^{th}$ term of the $AP: 10, 7, 4, \ldots$ is

Can any term of the $A.P.$ $242, 236, 230, \ldots$ be $0$? If yes,which term?
