Hello, I just want to know what they want me to do because i don't really understand the question. (iv) in total from the end of the nth day to the end of the 2nd day. Simplify your answer. These are the question it asks before; 17. The training programme of a pilot requires him to fly 'circuits' of an airfeild. Each day he flies 3 more circuits than the day before. On the fifth day he flew 51 circuits. Calculate how many circuits he flew: (i) on the first day (ii) in total by the end of the fifth day (iii) in total by the end of the nth day. I also have the answers to everything

    This is just a complicated way of writing compound interest.

    Oh, do you have the answer for (iii)? That one'll give you the formula for the rest, because it's the formula a for 'nth', or any day.

    Ok. I got the question before that fine- answer is \[\frac{ 2 }{ n }(3n +1)\]

    When they say 2nth, do I times the whole thing by two? Because thats what I understand it to mean.

    So stick the number of days in the formula as 'n' and work it out.

    it is asking you to figure out how many flights the pilot made each day

    No I mean the last one,where it wants me to calculate how many circuits he flew in total from the end of the nth day to the end of the 2nth day it says. I am not sure how to do that

    and it says each day was 3 flights more than the prior day. So to figure out how many flights were done the day before what should you do, add or subtract?

    subtract the difference

    14? I read it to say that there were 51 flights on the fifth day. So, yes. Subtract 3 from 51, and 3 from that answer to count backwards to the first day

    ok, so there were 14 flights on the fifth day, still subtract by 3 for each day

    ok, n= some number like an X in algebra. It is asking from some day to the end of the second day. So which day comes before the second day?

  38. anonymous

    That answer doesn't look correct for this problem. Are you sure you have the right answer for the right problem? Double check

    If we look at day two and place a 2 where the n is that would indicate that there were 19 flights on the second day, and we know that isn't the case. You will have to ask the teacher. Good luck

    Actually, I am home-schooled. I am the teacher! But no worries I will figure it out. :D Thanks for your time! I appreciate your trying.
