find the common ratio of each sequence:
1. 8,20,50,125......?
2. 0.48,0.9,1.8,3.6.....?

  • algebra 1 -

    to find the common ration, divide any term by the term before it.
    e.g. r = 50/20 = ....

    let me know what you come up with for both of your questions.

  • algebra 1 -

    The ratio of the first sequence is 2.5 so the recursive formula is going to be an= 2.5(an-1)
