This is just a short time filler. There are no prerequisite skills to have success, although some of the patterns are prime numbers, square numbers, and vowels. Some of the trickier ones have to do with patterns on a QWERTY keyboard and the first letters of progressions (U, D, T, C, C, S, ? is for uno, dos, tres…). I have included as answer key and both the answer key and problem sheet are given as Word documents and PDFs.
