Does an explicit formula for a sequence make sense assuming n = 2.5? Explain Choose the correct answer below
O A. It makes sense, but only if the term for n = 2.5 is an integer
OB. It does not make sense since n is the term number. It is not possible to have a term between the second and third terms.
OC. It makes sense since n is a variable, and variables can be any real number
OD. It does not make sense since n can be negative or positive but must be an integer.
