## VCabral1134 one year ago Plz help will medal and fan! Match each sequence with a function that generates it. a. f(n) = 3n, n ≥ 1 and n is an integer. e. f(n) = n^2+ 2, n ≥ 1 and n is an integer. b. f(n) = 2n(n+ 1), n ≥ 1 and n is an integer. f. f(1) = 48 and f(n) = 1^2 f(n− 1), n ≥ 2 and n is an integer. c. f(n) = 2(n+ 2), n ≥ 0 and n is an integer. g. f(1) = 48 and f(n) = 2f(n− 1), n ≥ 2 and n is an integer. d. f(n) = n− 1^n , n ≥ 1 and n is an integer. h. f(n) = n^n+ 1, n ≥ 1 and n is an integer. 4, 12, 24, 40, 60, …

That's Ok

Evaluate each function and find out the first two terms (the two starting values of n), and you will have a good idea where 4, 12, 24, 40.... fits.

I also have these 0,1/2,2/3,3/4,4/5... 48, 24, 12, 6, 3, … 3, 6, 9, 12, 15, … 3, 6, 11, 18, 27,...

I just need to find out which ones there not

Then I could figure it out

Example: a. f(n) = 3n, n ≥ 1 and n is an integer, i.e. f(n)=3n, n ≥ 1, n$$\in Z$$ means n={1,2,3,4....} Substitute n into f(n) gives f(n)={3,6,9,12,.....} Now look to see if {3,6,9,12,....} fits into any of the required sequences, and there you go!
