The $n^{th}$ term of an $A.P.$ is given by $T_{n} = 2n - 1$. Then,the $10^{th}$ term of the $A.P.$ is.........

Solve the equation: $1+4+7+10+\ldots+x=287$

Which term of the $A.P.$ $108, 103, 98, \ldots$ is its first negative term?

For a given $A.P.$,the first term is $5$ and the common difference is $12$. Find the $25^{th}$ term of the $A.P.$

For the finite $A.P.$ $1, 4, 7, \ldots, 118,$ find the $15^{th}$ term from the end.
