Francine and Genevieve were arguing about whether a recursive formula or an explicit formula was better to know to find the 376t
forsale [732]
Genevieve is correct. This is because if you only want to find a particular term of a sequence like in this word problem only the 376th term; the explicit definition will be more useful and quick. Recursive requires the previous numbers to find the next term and will take longer time to find the 376th term.
