Answer 1

11 as in 1st there is a gap of 1 digit then in 2nd 2 then in third 3 so 4th =7+4=11

Answer 2

Hey mate .....

Here is ur answer.....

I think the answer should be

11...

According to my logic ....

between first two series the difference is of 1..i.e 2-1

n in next two the difference is of 2

in next two its of 3 ...

therefore the next difference should be of 4 ...
so 7+4 = 11

thus it the next number is 11...
