    1. Well, even your first answer is incorrect.

    1st year -> $ 51 500
    2nd year -> $ 53 600
    .
    .
    .
    7th year -> $ 64 100

    Another way of looking at it is using the formula [mathT_n = a + (n-1)d[/math]

    Your 7th term, is given by

    2. Your increase is $ 2 100
    Your 6th year wage is $ 62 000.

    Percentage increase = (Increase/Initial) x 100%
