Question

Find the 6th term 9 18 36

Answer 1

Explanation:

This is a geometric sequence because any term divided by the previous term is a constant called the common ratio. r=36/18=18/9=2 A geometric sequence is expressed as

`a_n=ar^(n-1),\text{ where a=initial term, r=common ratio, n=term number}\\ \\ a_n=9(2^(n-1))\\ \\ a_6=9(2^5)\\ \\ a_6=288`

Answer 2

I think the answer is 288.

Explanation:

The rule seems to be multiplying the past number by 2. So, 9*2=18 and 18*2=36. If we continued that rule we would then get 72, 144, and the sixth term is then 288.

hope this helps :D
