What are the advantages of using an algebraic expression to represent a pattern rule, compared with describing the pattern in words?

Even if the pattern is only shown with 10 numbers you can solve to see what the 100th term would be with algebra

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
