Perhaps a better strategy is to make a new problem instead of frequently re-scoring due to incremental changes. BTW, the newly added last test case (#11) should return 2, not 1.

Jean-Marie Sainthillier on 2 May 2016

Yes, Test 11 -> 2

Tim on 5 May 2016

Test case 11 is still incorrect.

Jean-Marie Sainthillier on 9 May 2016

x = [i -2 -4i 8 16i] is an arithmetic serie ?

HH on 27 May 2016

Test case 11 fixed. Thanks.
