14.90hr with a 10% raise in hourly pay every year. what is my rate of pay after 2 years

14.90 x .10 = 1.49

14.90+1.49 = 16.39

16.39 x .10 = 1.639 round up to 1.64

16.39 + 1.64 = 18.03 per hour

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,
