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.
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.
To determine if the potential difference across a component is positive or negative, you can analyze the direction of current flow and the polarity of the voltage source. If the current enters the positive terminal of the component and exits the negative terminal, the potential difference is positive. Conversely, if the current enters the negative terminal and exits the positive terminal, the potential difference is negative. Using a multimeter to measure voltage can also provide a direct reading of the potential difference and its polarity.
No, because if the positive was 8, and the negative was -4, the difference would be positive four.
no
If you have a negative and a positive, then all you have is a negative and a positive. If you want to talk about performing some arithmetic operation on a pair of numbers where each number has one of those signs, we can certainly discuss that. But you'll need to be much more clear in your question. A great start would be to specify which arithmetic operation you're interested in, and we can go from there.

In an arithmetic sequence the same number (positive or negative) is added to each term to get to the next term.In a geometric sequence the same number (positive or negative) is multiplied into each term to get to the next term.A geometric sequence uses multiplicative and divisive formulas while an arithmetic uses additive and subtractive formulas.

positive
No, a positive minus a negative can be either or positive or a negative.
negative is below zero, positive is above
When it comes to numbers (this question was asked in the "Math and Arithmetic" category), adding a negative number to a positive number always equals a negative number.
