Generate Number Patterns (Sequences That Follow a Given Rule)

Something that happens again and again, like getting up in the morning and going to sleep at night; a template for needlework or other crafts, like a pattern for a zigzag edge; the stripes on someone’s shirt, which may alternate between two colors

The ceiling tiles are all rectangles, they just move across the room; the bricks in the wall aren’t always whole at the corner of the room, they alternate between whole and half each row; the mini-blinds are like small line segments, with space in between each one

4, 6, 8, 10, 12, 14, …

Double 5 is 10. Plus 1 makes 11.

19, 16, 13, 10, 7, 4, 1

Look for descriptions of the direction an object points, where the curves and line segments are, where new pieces are, or for missing or empty parts of a figure.

Increasing by 5s: 5, 10, 15, 20; decreasing by 5s: 20, 15, 10, 5.

Multiply by three: 1, 3, 9, 27, 81; divide by ten: 1,000, 100, 10, 1.

The second rule has two steps. If you double 3 you get 6, but if you double 3 and add 10 you get 16.

"Multiply by 2” goes on forever; a fuel gauge goes down as a car drives, and stops when the gas tank is empty.
