# C2 - Sequences (MEI) Watch

1. Hi I got stuck on this question and even with looking at the answers can't understand what is going on.

It is q12 on
http://mei.org.uk/files/papers/c210ju_ireg.pdf

Now I don't understand how I am supposed to work out any of this question. How do I work out how many buds/stems/nodes it has

And then that last questions just scares me
I don't even understand what I am meant to even attempt...

Any help will be much appreciated.
Thank you

I assume you have put the values for each term in a table?
Spot anything?

You have to recognize relations between the number of stages and
the number of stems/nodes/buds/leaves
Given three stages and the sum of above.
For rules you have to write down the number of stems by stages
For root stem use the 0. stage.
What is the relation between the number of the stage and the number of
the stems at the given stage.
Which type of sequence do you get, how many terms are in the sequence
and how can you summarize them.
For nodes how many terms do you summarize
And value of which term gives the number of buds.
For 3 stages you have the answers. Recongnizing the relations calculate the given values with the rules.
When you will get correct answers then generalize for n stages. What will be the rules for n stages.
THen you can answer the question easily for example when n=10
Leaves = 7*nodes
Fro last Q.
Leaves >200000 you have to solve this inequality for n
4. Sorry I am still confused as to how to do that last question. How do we just input 200,000 into the equation?
