How can you tell the difference between a coefficient, term, variable, and constant?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

C. because 6÷3=2 so 3 is half of six so 3/6

I'm not sure you can get negative in holes, but in the case of -3+5=2the total is 2.
