Question

Find the next three terms in the sequence. 24,20,16,12…. (If you could explain it that would be great too. It’s a bit confusing)

Answer 1

First term =a=24

common difference=d=20-24=-4

Formula

• a_n=24-4(n-1)

a_5

• 24-4(4)
• 8

a_6

• 24-5(4)
• 4

a_7

• 24-6(4)
• 0

Answer 2

the next three numbers should be 8, 4, 0

Explanation:

it reduces by 4 each time

24 - 4 = 20

20 - 4 = 16

16 - 4 = 12

12 - 4 = 8

8 - 4 = 4

4 - 4 = 0
