    Please help I know this question is relatively easy but I have totally forgotten how to do it. It is about Linear patterns.

    No. of Tables (T) - 2,3,4,5,6
    No. of Customers (C) - 8,12,16,20,24,28

    Now I know this part - 4T + ?

    But what would the corrective number be? (? = Corrective number btw.) And can you please explain how to get the corrective number. Thank you so much I know I sound kind of daft right now sorry

    You have worked out that it is 4T so multiply your T values by 4. You will get 8,12,16,20, 24,28.
    Now look at those new values and see what you have to add (or subtract) to get the corresponding C values. For example,
    When the first new T value is 8. The first C value is also 8. 8 + what = 8. You add 0. So it is 4T + 0 which is 4T
