Hello Manisha,

First number= 1

Second Number = (difference is 3 ) 1+3 =4

Third number = ( difference is double  3*2 =6 ) i.e. 4+6 = 10

Fourth number = ( difference is 6*2=12) i.e. 10+12 = 22.

So the next number is = ( difference is 12*2=24) i.e. 22+24= 46

I hoe your question has been answered properly.

All the best!
