In letter series, the letter A follows the letter Z.

The program will try to solve any problem of this type that you choose to propose. The only condition which must be met in order to approve any proposed series is that it must be logical and solvable by a human being. In other words, if the series were proposed to a person with a normal IQ (Intelligence Quotient), he or she would be able to solve it.

If you want to know if a series is valid or not, try it on another person.

Enter the series in the box and press the OK button to solve it.

The minimum quantity of numbers in the series is 4, while the maximum is 12

The numbers in the series must be separated by spaces.

The system also accepts scientific notation.

Letters cannot be combined, they must be only one character.

Lower case letters are not accepted. Use only capital letters.

The characters and order of letters are as follows:
