    1. note constant d = 2
    arithmetic sequence
    straight line of slope 2

  • Algebra -

    2. constant d again
    y = m x + b
    y = 2.3 x + 3

    3, whoa, climbing faster
    try
    y(n+1) = 3 y(n)
    geometric
    ratio is always 3
    or r = 3
    y = 1.4 * 3^(x)

    try x = 4
    y = 1.4 * 3^4 = 1.4 * 81 = 113.4
    it worked
