Yes, it is geometric and the ratio is 3/4. You can tell because you can divide each one by the one before and you get 3/4. (3/16)/(1/4)=3/4, (9/64)/(3/16)=3/4, and so on.
Hope that helps
P=1/5. factor out the p to get 4p-15pn=4/5p-3n and just solve to get p=1/5
<span>Five less than a number is at least -28
n-the number
n - 5 < -28 |add 5 to both sides
n < -23
