**Answer to Number Riddle:**

If you carefully observe the sequence you will be able to crack it in less than 2 minutes.

Check the alternate numbers, they are all prime numbers, but the numbers in between might be difficult to crack.

Here’s what the sequence follows;

It first lists the prime number and than they number of letters in the spelling of that number.

So the given sequence is as follows;

2 = Two = 3

Hence next number is 3

followed by the next prime number that is 3

3 = Three = 5

So next number is 5, followed by next prime number which is 5

5 = Five = 4

So next number is 4, followed by next prime number which is 7

7 = seven = 5

So next number is 5, followed by next prime number which is 11

11= Eleven = 6

So next number is 6, followed by next prime number which is 13

13 = Thirteen = 8

**So the next 2 number in the sequence are 13 and 8.**
