what's the explicit formula to the sequence 1/2 , 1 , 3 , 12 , 60 , 360 , 2520 , ...? Multiplies by one larger number each time but how to put that into an explicit formula?

Any hints on how to prove this? What can we use a a proper subsequence, knowing that a proper subsequence is any subsequence except for the sequence it self.

A sequence has a common ratio of R=-2 so if G3=7 what is G5? A. 3 B. -14 C. 28 D. -28

is -64,-16,-4 an arithmetic sequence, geometric sequence or neither?

How do I go about proving limits for given sequences and series, for example how would i prove that the limit when x tends to infinity of n^(1/n)=1?

A sequence has a common difference of D=-4 so if A2=-5 what is A5? A. -9 B. -13 C. -17 D. -21

a2= a3= a4= a5=
