Question

And it crooked....sorry!

what is the value of the 9th term in the following geometric sequence?3,12,48,192...

Answer 1

geometric sequence

an=a1(r)^(n-1)
a1=first term
r=common rati
common ratio is 4 because 3 times 4=12
first term is 3

an=3(4)^(n-1)
9th term
a9=3(4)^(9-1)
a9=3(4)^8
a9=3(65536)
a9=196608

answer is 4th option
