Is that it?

I was thinking more along the lines of the following, where DR is the
digital root (the sum of the digits repeated until you get to a single
digit), why are these two sequences the same?

2^0 = 1, DR = 1
2^1 = 2, DR = 2
2^2 = 4, DR = 4
2^3 = 8, DR = 8
2^4 = 16, DR = 7
2^5 = 32, DR = 5
2^6 = 64, DR = 1
2^7 = 128, DR = 2

11^0 = 1, DR = 1
11^1 = 11, DR = 2
11^2 = 121, DR = 4
11^3 = 1331, DR = 8
11^4 = 14641, DR = 7
11^5 = 161051, DR = 5
11^7 = 1771561, DR = 1
11^7 = 19487171, DR = 2

I'm thinking it's because the digital root is a Mod(9) calculation and 11
% 9 = 2. But I may be losing the plot.

On reflection, I see that is the reason. I've been over-thinking it and
not fully understanding the fundamentals.

Thanks.

Or, possibly not. I'm feeling a little fragile at the moment and I need to think about this. It's all good, only numbers and a bit of a puzzle,
should be fun.

Hello Phil,

Would you care to post a pointer, or a solution with the usual
obscuration?

It's been long enough, here's the answer:

214358881

That might be enough to give the rule away, but if not, here's a
rot-13 explanation:

Ah, very good. If I had realized it was such a reasonably structured
question, I may have tried harder. However, I doubt I would have had the insight to find the solution. I'll have a better understanding of the type
of question you may pose, when I see future posts from you.

Best wishes,

Yes, the first four of the entries are blank.

Are you sure that the last number shouldn't be 948617? If it is
948617, then 2324788 may come next.

What's the thinking here?

Now you have me intrigued! However, the 7th term is indeed 948717.
As an extra pointer, the subsequent terms become incredibly predictable
very quickly at this point, until you hit the 25th term.
