So i have to find the first 5 terms of each sequence; 2^x-1. Would I start at 0? I mean is 0 a natural number

  1. if x refers to the term number, then it must be a natural number. The first of the natural numbers, sometimes called the counting numbers, is 1
    term(x) = 2^x - 1
    term(1) = 2^1 - 1 = 1
    term(2) = 2^2 - 1 = 4-1 = 3
    term(3) = 2^3 - 1 = 8-1 = 7
    etc.
