Question

Find the common ratio of the geometric sequence whose first term is 3 and sixth is 96.

Answer 1

Help/

Answer 2

ummmm...... i don't really understand the question :P what do you mean, the common ratio??? like, the nth term?? we can't do THAT unless we have all the terms.

Answer 3

first term=a=3
6th term=T6=ar^5
subistitute a in the 2nd equation and solve

Answer 4

3r^5=96
r^5=96/3

Answer 5

5th root to both sides and u get the ratio ;

Answer 6

so r = 2

Answer 7

what does ar means?

Answer 8

a=First term .
r=common ratio .
where the nth term in G.s =
ar^(n-1)

Ohhhhhh..Thanks! :D
