    Take a guess that the answer is a line.

    Use any to points where the term number is x and the term value is y. Sove for the slope and intercept.

    Terms 2 and 4 would give:
    m * 2 + b = 10
    m * 4 + b = 18

    m = (18 - 10) / (4 - 2) = 8 / 2 = 4

    If m = 4, what is b? (just substitute)
