Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

A number 8 more than 6 th term of the sequence 3 , 5 , 7 , 9 , . . . is

(a) 21

(b) 24

(c) 30

(d) 34

CONCEPT TO BE IMPLEMENTED

If in an arithmetic progression

First term = a

Common difference = d

Then nth term of the AP

= a + ( n - 1 )d

EVALUATION

Here the given sequence is

3 , 5 , 7 , 9 , . . .

It is an arithmetic progression

First term = a = 3

Common difference = d = 5 - 3 = 2

6 th term of the sequence

$\sf = a + (6 - 1)d$

$\sf = a + 5d$

$\sf = 3 + (5 \times 2)$

$\sf = 3 + 10$

$\sf = 13$

Now the number 8 more than 6 th term of the sequence then we get

= 13 + 8

= 21

FINAL ANSWER

Hence the correct option is (a) 21
