Answer 2

The 10th term is not 40. It is FALSE.

Given,

In an A.P., an =3+4n

To Find,

If the 10th term will be 40?

Solution,

We can solve the question as follows:

It is given that the nth term of an A.P. is given as 3 + 4n. We have to find out if its 10th term will be 40.

$a_{n} = 3 + 4n$

To find the 10th term, we will substitute n = 10 in the above formula.

$a_{10} = 3 + 4*10$

     $= 3 + 40$

     $= 43$

Therefore, the 10th term is equal to 43.

Hence, the 10th term is not 40. It is FALSE.
