No luck there! Can anybody else help me by solving them or at least some?

Are you certain your friend isn't winding you up? :)

For example, sequence 8 has leading 0s on some of the numbers, this would lead me to assume that they are not mathematical, if they are even valid at all.

Can you admit defeat on one and ask for the answer? That way we'll have some idea what your friend has in mind.
For #5, the second number is 11 times the first number... not sure how that helps :)

Actually this is wrong. I won't divulge where you made the error as these questions form part of an admission test to several high IQ societies inlcuding: ISI, CIVIQ, Cerebrals, etc... In an effort to preserve the integrity of these tests you should delete this question and any reference to answers.

Does this paragraph below sound familiar?

"This exam composed of fifty number sequences has been created in the spirit of Logima Strictica 36 and Logicaus Strictimanus 24 by Robert Lato and the Non-Verbal Cognitive Performance Examination by Dr. Xavier Jouve. This test is currently accepted as an entrance exam by the Glia Society, ISI-Society, Sigma Society, Camp Archimedes, StrictIQ Society, Giga Society, and other societies may also choose to accept it.
A current score list and norming can be found on the links provided, and in the statistics section of Gliaweb.
I encourage you to have fun, this test requires no knowledge whatsoever, just the ability to detect numerical patterns.
Take as much time as you need. References are allowed. Please DO NOT share or publish answers at any time with any other person, or publish this exam without my permission."
