Here, we want to check if the given statement is a statistic or a parameter
While a parameter describes the whole population, a statistic describes a sample
From what we have in the question, the data completely describes each set of staff in the mathematics department
Thus, we can say it is a statistic
It represents a geometric sequence because it has a common ratio of 2.
In fact, a sequence is said to be geometric if any two adjacent elements are in the same ratio. In other words, if you choose any index and consider the two consecutive terms
and
, you have
no matter which index you chose. In your case, the next term in the sequence is always the double of the previous one, so the ratio between two consecutive terms is always 2, and the series is geometric with common ratio 2
