A Puzzling Palindromic Sequence
Sonja Sharp (email)

Sonja Sharp from Cape Town, South Africa has a problem
with this sequence and was wondering
if I could assist her. She has to add the smallest number
possible to make it a palindromic sequence:

6 , 9 , 2 , 4 , 1 , 8 , 11 , ?

Sonja and I would really appreciate some assistance if you have some time!
What's more, she wrote me, is that she finally got the number to complete
the sequence. However, the answer does not make any sense to us...
the answer (a guess) was number 4 !!!
Can someone figure out how that was supposed to be the solution ?
Sonja and myself would be very impressed !

Jennifer Hunter assumes
the answer is 4... because of  ROMAN NUMERALS

6 , 9 , 2 , 4 , 1 , 8 , 11 , ?

equates to

vi, ix, ii, iv, i, viii, xi, ?

so the logical answer is iv
since after appending iv we get the palindromic image

viixiiiviviiixiiv

So it seems that Roman Numerals are back in town
since WONplate 16
