Question 103052: My text book is Glenco PreAlgebra page 95. My question is with problem #3. I am suppose to write the rule for the pattern 63, 48, 35, 24. I know it is n-15, then n-13, then n-11 but I can't figure out how to write a rule that will work for the whole pattern. thanks.

write the rule for the pattern 63, 48, 35, 24.
a(1) = 8^2-1 = 63
a(2) = 7^2-1 = 48
a(3) = 6^2-1 = 35
a(4) = 5^2=1 = 24
------------------------
a(n) = (9-n)^2-1
