>>14125497I was looking at it, but not wanting to waste my time again, I searched for answers and found an answer dump (without explanations):
https://pastebin.com/xhNq1TZDIt's a really stupid test, imo. Some questions have more than one defendable answer, and not as much of a problem, some answers have more than one defendable process.
For Q20, here are some of the ways you can get 7 x's:
-- sneakily complete the odd-number sequence at the start rather than the end: 7 5 3 1
--- have a mod-8 cycle: 5 3 1 7
--- minus 4 on the odd-numbered positions (5, 1), plus 4 on the even-number positions (3, 7)
--- (5 + 3) = 8, (1 + 7) = 8
--- 5 + 3 = 8 (no space after the lone x)
--- 5 + 3 - 1 = 7 (alternating operations)
Even though 7 x's is the expected answer, you could also, among many other defendable answers, just say that the answer is 'o', with x's representing 1 and o's representing -1.
5, 3, 1, -1.
I'm convinced that Ivan Ivec just doesn't have the IQ required to design high-range IQ tests.
