The terms a approach 8 as n becomes large. The terms a approach infinity as 8 approaches n. The terms a approach infinity as n become large. The terms a approach 8 as n becomes small. (c) What does it mean to say that lim = co? The terms a approach zero as n becomes large. The terms a become large as n becomes small. The terms become small as n becomes small. an The terms a become small as n becomes large. The terms a become large as n becomes large. an
