The Science Times section of the New York Times, Tuesday, May 23, 2023, had an article on Sloane's Online Encyclopedia of Integer Sequences. A sidebar had four sequences for the reader to identify. Here's your chance to do so; identify the next in sequence:
- 0, 1, 8, 11, 69, 88, 96, 101, ...
- 1, 11, 21, 1211, 111221, 312211, ...
- 5, 8, 12, 18, 24, 30, 36, 42, ...
- 14, 18, 23, 28, 34, 42, 50, ...
Of course it would be no fun looking up the answers in the OEIS (or the NYT).
Part B is "counting" the number of same dights in the previous number in the series. 1, one one (11), two ones (21); one two, one one (1211), one one, one two, two ones 111221, etc.
