Question

Find 11th term of the A.P. 10.0, 10.5, 11.0, 11.5, ...

Answer 1

11th term of the A.P. 10.0, 10.5, 11.0, 11.5, ...

Here

First term (a) = 10.0

Common difference of the A.P. (d) = 10.5 - 10.0

= 0.5

Now, as we know,

`a_n = a + (n - 1)d`

So for 11 th term

`a_11 = a + (11 - 1)d`

`= 10.0 + (10)(0.5)`

= 10.0 - 5.0

= 15.0

Therefore  the 11th term of the given A.P is `a_11 = 15.0`
