    no. It started at 1, then added 2, then added 4, then added 8. What would be the next number added?

    Each line is adding 2 times the last number added, so when x = 5 y = 1 + 2 + 4 + 8 + 16

    from there if you know your exponents you should see the pattern. |dw:1434049509172:dw| Your y-values are 1 less than 2^x

    We have in the third column and expression for x. The second column is y. What's the relationship between numbers in the 2nd and 3rd columns?

    subtract the numbers in the 3rd from those in the 2nd and tell me what you get?

    so if you subtract 1 from 2^x you get y
