## Next in the Sequence

Here is a series of numbers. What is the next number in the sequence?

1

11

21

1211

111221

312211

13112221

The next number in the series counts the previous numbers. Thus the first number is 1, which is one 1, or 11. To describe 11, you have two 1’s, or 21. Now you have one 2 and one 1, so the next number is 1211. The solution is to continue describing the previous number using only numbers.

If 6051=234789 which two not in sequence. You can chane the numbers. But 4 left side and 6 left side.

Two of the right side of equation not belong to the left side

Or two of the right side will be in sequence to come

Please call me if you may . I will pay
