Answer:

3) b; (C, S, T, T, S, C)

4) Short, Tall, Medium

Explanation:

3)

(a) Each odd-numbered item is "Circle", so the 18th item will be "Square"

(b) The 1st and 6th items are "Circle", and the sequence is 6 items long. The last item in the 3rd repetition will be the 18th item: "Circle". This rule gives the desired 18th item.

(c) "Circle" is the first of a 4-item sequence. The 18th item will be the second item in the 5th repetition, so will be "Triangle".

__

4) We presume the given 3 items are repeated, so the next 3 items will be the same: Short, Tall, Medium.
