ANSWER:


























You naughty cheater


























add together the digits until you get a 1-digit number. Take two to the power of the result.
If the number is already in the sequence, add 1 until you get a new one.

a(n)=the 180° rotation of the nth number which is still a number when read upside down (i.e composed only of 0,1,2,5,6,8,9)




The problem with this thread is that you get a lot of sequences like 6,6,3,3,8,3,5,5, and no one's going to guess that it's "every other digit of 6√131".

I'm sorry. At least it's not

"every other digit of 6√131".

for some reason "the absolute value of the difference between the last entry and the sum of all the entries up to and including the last entry" just ends up generating fibonacci's sequence:

Code: Select all

1, 0, 1, 1, 2, 3, 5, 8, etc

[Hdjensofjfnen]

Code: Select all

1, 2, 4, 10, 195, 190, 197, 607, 1128, 16542, 12106, 18383, ...

Hint: Every term of this sequence is based solely on the previous one. The rule is not particular to the sequence beginning with 1; it can also begin with any other nonnegative integer. Some numbers, including the number 298, are "gardens of Eden" -- no number leads to them.

Moosey's sequence is 2p-3 where p is the nth prime, so it goes:

Since we obviously need more sequences, here are some more which should be guessable (despite similarities, on the surface they are not related):

Unique final repeating population of an orthogonal line of contiguous on cells in B3/S23 (which is why the tenth term — corresponding to a pentadecathlon — is missing).

[Moosey]

Moosey's sequence is 2p-3 where p is the nth prime, so it goes:

It matches that for the first two entries but no farther
