Question

A sequence is created from the function k(n) = 2n + 3, where n represents the position of the term of the sequence. The sequence does not begin with 0. Which list represents the 1st 5 terms of the sequence.

Answer 1

Substitute the n value into the equation. The n repersents the 'nth' term.
K (1) = 2(1) + 3
      K = 5
Therefore, when n = 1, K = 5
Same goes t any other term.

K (3) = 2(3) + 3
     K = 9
So, when n = 3, K=9

Just keep applying the same rule. Also, make sure that you answer it with a sentence at the end. This should always help you and the marker see that you are confidence with your answer...
