Answer:

Step-by-step explanation:
Given the formula for calculating the displacement of a body as shown below;

d = displacement
v = final velocity
a = acceleration
t = time
To make the acceleration a the subject of the formula, the followin steps must be taken;
Step 1: Subtract vt from both sides of the equation

Step 2: Divide both sides by t²


Step - by - step - explanation
So first find out the pattern. As you can see it just minuses 2 each time. So first
18, 16, 14, 12 (then minus another 2) equals 10, 8, 6, 4, 2.
So 2 is the ninth of the pattern, so 2 will be your answer.
Hope this helps.
