The question isn't too clear but suppose that T(N) actually generates a sequence of numbers for values N=1,2,3,... where the Nth number in the sequence is given by 4N-1.

Then, what is the third term in this sequence?? Firstly, what must N be to represent the 3rd term? So substitute it in and see what it is.

4n-1 means it starts at -1 and u add 4 so it goes to 3, then 4 is 7, then 4 is 11, do you understand?? I'm year 9 and this is quite confusing so it's not your fault good luck. (I hope I did it right cus I'm set 1 hahaha)
