6,12,24,48,96... when we multiply by 2
-6,12,-24,48,-96.... when we multiply by -2
a) q can be 24 or -24
b)p/r=6/96 =-6/-96= 2/32=1/16
c) a(n)=6*2^(n-1)
386=6*2^(n-1), 386/6=2^(n-1), 64,333(3)=2^(n-1),
we will not be able to find whole number n for number 386, so 386 is not a term in this sequence, because it does not follow the rule of this sequence
