Question

Please give me answer of question no 3

Answer 1

Answer:

$a_2=3$

Step-by-step explanation:

Given: if n is even no. then $a_n=2n-1$

          if n is off no. then $a_n=2n$

To find: value of $a_n$ when n = 2

Say $a_n=2n-1$  is 1st function.

and $a_n=2n$ is 2nd function

Since n = 2 is a even no.

we select 1st function.

Put n =  2 in it

we get,

$a_2=2\times2-1$

Now find product of 2 and 2, we get

$a_2=4-1$

subtract 1 from 4, we get

$a_2=3$

Therefore, $a_2=3$
