🔁 Patterns

Does a pattern repeat or grow?

Some patterns go round and round. Some get bigger every step. Find out which is which, and why “step 10 is double step 5” is a trap.

A repeating pattern has a core that comes round again and again, so to find a far-away piece, count in whole cores and look at what’s left over. A growing pattern changes by the same rule every step. To predict a far-away step, use the rule. Doubling step 5 doesn’t give step 10, because the starting piece only shows up once.
