Given the arithmetic sequence 3, 7, 11, 15, what is a1, the first term? what is d, the common difference? find the 151st term of this sequence. what formula did you use? be sure to show your work. you.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
