Which number is next 2 7 8 3 12 9

Next number is 4.

Step-by-step explanation:

Given :  2 7 8 3 12 9

To find : which number is next

Solution : We have given that  2 ,7 ,8, 3 ,12 ,9.

We can see this  it has two group ( 2,7,8) ;( 3 , 12, 9)

Second group is created by first

First number on adding 1 in 2

Second number on adding 5 in 7

Third number on adding 1 in 8

Now we can create next group by second group

3 + 1 = 4

12 + 5 = 17

9 +1 = 10

Then next group would be ( 4 ,17,10 )

Therefore, Next number is 4.
