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.

How can you determine whether the arithmetic sequence has a positive common difference or a negative common difference?

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.

What is the difference between an arithmetic sequence and a geometric sequence?

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.

How can doctors determine positive or negative blood types.?

Doctors can determine positive or negative blood types by administering a test. The difference between positive and negative types is the presence of the RH factor. Positive blood types indicate the presence of the RH factor while negative blood types do not have this factor.


Does a negative and positive equal a negative?

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.
