Determine the Arithmetic Progression whose third term is 5 and the seventh term is 9.

How many students failed in all three subjects English, Hindi and Mathematics ?

The fifth term of an Arithmetic Progression is 20 and the twelfth term is 48. What is the common difference?

The 10th term of the A.P. 1, 5, 9, 13, ..., is :

It is observed that in each case, every term except the first term bears a constant ratio to the term immediately preceding it. Such sequences are called:

If : $a + b + c = 14$ and $a^2 + b^2 + c^2 = 96$, then $(ab + bc + ca)$ is

Select the correct set of symbols which will fill in the given equation.
