In determining the n to the power of t h end exponent term of asequence, using a recursive process differs from using an explicitformula in that with a(n):
a. recursive process, you need to generate all the previousterms of the sequence.
b. explicit formula you can not generate the n+1th term of thesequence directly.
c. explicit formula you need to generate all of the past termsof the sequence.
d. recursive process, you need to generate all the future termsof the sequence.
