Question

the 10th term of an ap 11, 15, 19 is​

Answer 1

Hola!

Here's your answer.

Here, a=11.

d=15-11=4.

n=10

So, the term of an A.P. is given by

a+(n-1)d

11+(10-1)4 ==》11+9×4 ==》11+36= 47.

Therefore, the 10th term of the given A.P. is 47.

Thank you

Answer 2

Given:

An AP.

11, 15, 19...

To find:

The 10th term of the AP.

Solution:

The 10th term of the AP is 47.

To answer this question, we will follow the following steps:

As we know that the nth term of an A.P. is given by

${n}^{th} \: term = a + (n - 1)d$

Now,

As given, we have an A.P.

11, 15, 19...

Now,

We have,

First-term = 11

Common difference = 15 - 11 = 4

So,

The 10th term of the A.P. is

$= 11 + (10 - 1) \times 4$

$= 11 + 9(4)$

$= 11 + 36$

$= 47$

Hence, the 10th term of AP is 47.
