Answer:

(a) The sum of the previous term and 9

(b) 36, 45, 54

Explanation:

Given

Sequence: Arithmetic Progression


0,9,18,27

Solving (a): Describe the relationship in each term

First, we calculate the common difference (d)

In arithmetic progression:


d = T_n - T_(n-1)

Take n as 2


d = T_2 - T_(2-1)


d = T_2 - T_(1)

Where


T_2 = 9\ and\ T_1 = 0


d =9-0


d =9

The relationship is: The sum of the previous term and 9

Solving (b): The next three terms

As said in (a) each term is derived from a sum of 9 and the previous term

So, we have:


Next\ Term = 27 + 9 = 36


Next = 36 + 9 = 45


Next = 45 + 9 = 54

Hence, the next three terms are: 36, 45 and 54
