To use four consecutive digits, start by choosing any digit from 0 to 6, as these are the only starting points that allow for four consecutive numbers (e.g., starting from 0 gives you 0, 1, 2, 3; starting from 6 gives you 6, 7, 8, 9). Once you have your starting digit, simply list the next three digits in sequence. For example, if you start with 3, the four consecutive digits would be 3, 4, 5, and 6.

Oh, dude, consecutive identical digits are just fancy words for when you have the same number back-to-back. Like when you see 22 or 777 in a row. It's not rocket science, just a fun little pattern that shows up in numbers.
Depends on where you start.
