Question: Is 3 average of the sequence?

Statement 1: There are 3 numbers in the sequence

We have no numeric value of any one of those 3 terms and neither do we know any relationship among the terms in sequence hence

NOT SUFFICIENT

Statement 2: The mode of the sequence is 3
i.e. 3 is most frequent terms of the sequence but it doesn't ensure whether 3 is the average or not hence
NOT SUFFICIENT

Combining the two statements

Since we have three terms and 3 is the mode therefore Median of the set will also become 3 but we still can't comment about the Mean of the terms hence

NOT SUFFICIENT

Answer: Option E
