In order to determine whether or not this is an arithmetic sequence, there must be at least 3 numbers.
To check whether it is an arithmetic sequence, verify whether the difference between two consecutive numbers is always the same.To check whether it is a geometric sequence, verify whether the ratio between two consecutive numbers is always the same.
For any index n (>1) calculate D(n) = U(n) - U(n-1). If this is the same for all integers n (>1) then D is the common difference. The sign of D determines whether the common difference is positive or negative.
There is no simple answer because the position of the missing number is not known. Furthermore, it is not clear whether the sequence is an arithmetic, geometric or some other sequence.
If the terms get bigger as you go along, the common difference is positive. If they get smaller, the common difference is negative and if they stay the same then the common difference is 0.

It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.

The question cannot be answered because two terms are not enough to determine whether the sequence is arithmetic or geometric (or something else).
For any index n (>1) calculate D(n) = U(n) - U(n-1). If this is the same for all integers n (>1) then D is the common difference. The sign of D determines whether the common difference is positive or negative.

There are different answers depending upon whether the sequence is an arithmetic progression, a geometric progression, or some other sequence. For example, the sequence 4/1 - 4/3 + 4/5 - 4/7 adds to pi
imaginary
If they have no common factors other than 1.
The answer will depend on where in the sequence the missing number is. It is not clear whether the dash is used as a minus sign or to separate numbers in the sequence.
