First we need to arrange this data.
00:03
So first is 7, 7, then 9, 10, then 13, 17, 19, 21, then 23, 26, 28.
00:53
Now we have to find q2.
00:56
The formula of q2 is equal to n plus 1, 1 by 2.
01:04
Here n is equal to 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13.
01:16
N is equal to 30.
01:19
For 15 by 2, that is 7th term, will be q2.
01:26
7th term means 1, 2, 3, 4, 5, 6, 7.
01:31
So 19.
01:34
Next we'll find q1.
01:36
This formula is n plus 1 into 1 by 2.
01:41
4 that is 14 by 4 14 which is equal to 3 .5 3 .5 means 1 2 3 this is 3 this is 4 so in between here this term will be so it's equals to 10 plus 12 divided by 2 which is equal to 11 next we have to find q3 2 is equal to n plus 1 into 3 by 4 terms which is equal to divided by 4 10 .5.
02:39
10 .5 means 1, 2, 3, 4, 5, 6, 7, 8, 9, 10...
