nth term questions
Examples:
A geometric sequence with a positive ratio has 3rd term 18 and 7th term 1458. Find the value of the 10th term.
A geometric sequence has the first 3 terms 2,2k,9k+5,…
Given that k > 0, find:
(a) The value of k.
(b) The 7th term of the sequence.

(c) Find the value of a8 - a6
A ball is dropped from a height of 5m above the floor. After bouncing once, it reaches a height of 4m above the floor. The height reached by the ball after each subsequent bounce forms a geometric sequence.
(a) Find the maximum height above the floor the ball reached after the 3rd bounce?
(b) Find the minimum number of times the ball will bounce before the maximum height reached above the floor is less than 18m.
