hello everyone,
I am preparing for an exam. In brief, my exam practice book shows the following number sequence:
20, 30, 50. And asks what is the next number in the sequence?
The answer that the book gives is 80.
Years ago, when I took a math class, i remember there being a formula for arithmetic and geometric number sequence problems. Now, as I look at these formulas I can't seem to understand which of these formulas applies here. I understand that there is a steady increase on top of the cumulative total.
Term 1 Term 2 Term 3 Term 4 so on and so forth ...
term 1 + 10 term 2 + 20 term 3 + 30
= 20 = 30 = 50 = 80
My question, is there a formula that would tell me the 300th term in this sequence?
your help is much appreciated,
thanks
