Hello Aspirant,

If you concentrate on the series properly then you will find that the next number is product of digits of it's previous number like 56 is the product of 8 & 7 and similarly 30 is the product of 5 & 6 so according to this pattern, the next and last number for this series would be 0 because the product of 3 & 0 is always 0 and once the zero comes in this series then it cannot proceed forward because with zero there is no number to be multiplied .

I hope you got an answer.

Good Luck!!!
