What number should logically replace the question mark?
26, -39, 58 ½, -87 ¾, ?
Update: Thanks for pointing out the missing question mark! I added it in.
I didn't catch a question mark other than in the non-numerical portion of the question... and seeing as how the numerical portion is found to be irrelevant to the overall question itself, the non-numerical part actually constitutes the entirety of the question. My answer is that no number should logically replace the question mark.

Each number is -1.5 times the previous number. So the answer is 131 and 5/8
ReplyDelete131 5/8
ReplyDeleteTHERE IS NO QUESTION MARK IN THE SEQUENCE!
ReplyDeleteTHE ONLY QUESTION MARK IN THE POST IS IN THE QUESTION ITSELF!
And it's grammatically necessary, so no number should replace it.
Too snarky?
131 5/8 common ratio = -1.5
