### Solved Examples

**Question 1:**Find first term of arithmetic progression whose 7th and 10th terms are 35 and 59 respectively.

**Solution:**

Let 'a' be the first term. Now we have to find the value of 'a' by using given instructions.

Given: 7th term, a$_7$ = 35 and 10th term, a$_{10}$ = 59

We know that the general term of AP is, a$_n$ = a + (n - 1)d

$\Rightarrow$ a$_7$ = a + 6d = 35

or a + 6d = 35 ...........(i)

and a$_{10}$ = a + 9d = 59

or a + 9d = 59 ..............(ii)

The value of 'a' can be found by subtracting equation (ii) from equation (i)

a + 6d = 35

a + 9d = 59

- - -

-----------------

-3d = -24

-----------------

$\Rightarrow$ d = 8

Substitute the result of d in equation (i)

a + 6 $\times$ 8 = 35

a + 48 = 35

a = -13

The value of a is -13.

**Question 2:**From 8 men and 5 women, four persons are being selected to form a committee so that at least 2 women are available in the committee. In how many ways can it be done?

**Solution:**

The possible number of ways are:

2 women and 2 men = $^5$C$_2$ $\times$ $^8$C$_2$ = 280

3 women and 1 man = $^5$C$_3$ $\times$ $^8$C$_1$ = 80

4 women only = $^5$C$_4$ = 5

So total number of ways = 280 + 80 + 5 = 365
