Complete thesequence puzzle

This weeks puzzle in the Saturday times is a complete the sequence one.
I have studied it and haven't found the solution.
I haven't looked at the answer either but you're welcome to have a go and I will check.
The numbers are:-
02,50,20,59,18,43,74,66,47,34,81,95,??,??,??.
Most of the numbers are reversible, but then you are left with 66 and 50 and 3 numbers to find so I don't think that is the way to go.
I also tried converting them to binary and hexadecimal but didn't find a pattern

@venda

02, 05,20

It's palindromic around the 66

This weeks puzzle in the paper is another number link one.
Again, I haven't looked at the answer.
I'm not really very good at these.I probably tend to overthink them.
Anyway, I thought puzzle was to do with historical dates.
I tried the other numbers in different calendars but couldn't match them up + I can't find an historical link in English history to 1111.
Anyway, if you're still reading , here's the puzzle:-
391 is 1066
400 is1111
453 is 1215
642 is1605
685 is1666
700 is when?

@wolfgang59
Except in one case, which could be a typo, the separate digits on the left add up to the total of the separate digits on the right. The solution is most likely a year, e.g., 2005 or 2014.

Did the puzzle actually say "700 is when?"

When implies a date doesn't it?
Anything to do with places?
Hastings, Runnymede, Westminster, London

Hi Venda

I reached the same conclusion as Andy. If the 'errant' one was meant to be

450 = 1215, then it would work (450 instead of 453)

That would be my guess at the typo. If it isn't, be interesting to see what the link is. Can't see it being historical, 1111 is not a year noted in British history!

Got it!
Looking at the digits on the right hand side, the highest is 6, so did some work on different 'number bases', the lowest it could be is 7.
Thank gooodness, when you convert 1066 in base7 to base 10 it is 391 (1 x 343(7 to power 3), 0 x 49, 6 x7 and 6 x1)
The others work too
So I need to change 700 to base 7, lo and behold it is 2020.
