My brother and I spent some time hanging out this weekend and he taught me a specific sequence of numbers during a particular activity.
58, 567, 57, 578, 58, 58
What does it represent and what were we doing?
Some more sequences:
357, 356, 357, 45, 346, 357
135, 245, 235, 24, 235, 135
357, 467, 457, 46, 457, 357
81012, 81011, 81012, 910, 8911, 81012
6810, 7910, 7810, 79, 7810, 6810
81012, 91112, 91012, 911, 91012, 81012
91012, 91113, 91112, 911, 91112, 91012
Hints:
- Our activity didn't require electricity
- Taught is a key word. These sequences are memorised for a specific purpose.
- The sequence lengths are important. To elaborate upon this, the fact that there are the same number of groups per sequence is very useful information.
- My brother knows these sequences very well because he uses them for a living.
