Question

Find the 11th term of an AP: 10,7,4,........-62

Answer 1

SOLUTION:

Given:

A.P. is 10,7,4,........-62.

To find:

The 11th term.

Solution:

We know that, formula of Arithmetic Progression;

${}^{a} n = a + (n - 1)d$

So,

We have,

•Last term,l= -62

•common difference, d=-3

Now,

11th term from the end= l-(11-1)d

=) -62 -(10)(-3)

=) -62 -(-30)

=) -62 +30

=) -32

Thank you.
