Complete the sequence:
8, 6, 7, 3, 6, 5, 4, 5, 5, 2, ?
I think the missing member of the sequence is
6
Because
These are the number of segments used to represent a number on a 7-segment display, counting backwards from 10, i.e, '10' requires 8 segments, '9' requires 6,..., '1' requires 2 and finally '0' requires 6.
