Answers,explanations and assessments

In a numerical sequence test, it is necessary to identify a pattern that is occurring in the sequence. The numbers in the sequence may be progressing, or they may be decreasing, and in some cases, they may be both progressing and decreasing within the sequence. It is up to you to determine why this is occurring and to either continue the sequence or to provide a missing number within the sequence.

Fill in the missing number(s) indicated by the question mark(s) in each question. Number sequence test a numerical sequence test it is necessary to identify a pattern that is occurring in the sequence. The numbers in the sequence may be
