    Please Help With This Extra Credit Math Challenge Problem

    I was given 2 sets of numbers and I have to guess the next 2 numbers in each set .

    14 23 28 33 42 51 59 68 (what would the next 2 numbers be?) the pattern was 9, 5, 5, 9, 9, then went down to 8 and then back to 9 again...

    my 2nd set was:
    2.50 2.90 3.30 3.70 4.10 4.50 and then I have to find the next 2 numbers and find out where does this appear in real life?

    any help at all would be greatly appreciated.

    The second one's easy: add 0.4 to get the next number. As to where it appears in real life, my answer would be "in a stupid math challenge test."

    As for the first one, I'm still trying to work it out. It looks tricksy to me.

    It would be really stupid if this is it but the answer is maybe 77 and 86. This might be the same question in an interview questions brain teasers.

    Its the number of the streets for the stops of the Lexington Ave subway line.

    I was really, really hoping the answer was not going to be something as inconsequential and non-mathematical as this. Teachers of mathematics have no right to serve up rubbish like this as homework questions.
