Instructions
You will be given a list of sequences, and the goal is to figure out the missing number in each of the sequences.
The answer can be in form of an integer or fraction e.g. 3/4
. An answer in the form of a fraction has to be in irreducible format.
E.g. 1/3
is a potentially correct answer, but 2/6
will not be accepted.
You can move to previous/next sequence by hitting the Ctrl + LeftArrowKey
and Ctrl + RightArrowKey
arrows keys.
Each test has a time limit of 10 minutes. After the time is up, your anwsers will be automatically submitted. Each correct anwser is +1, no answer 0, wrong answer -1.
