Given a 1=4, r=-5, n=7 what is the value of a(n)?

-29

Step-by-step explanation:

If and r = -5 for the rate or difference between terms, then the sequence is 1, -4, -9, .... etc.

To find a(7), continue the pattern until you find the 7th term.

1, -4, -9, -14, -19, -24, -29....

a(7) = -29

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
