​

Answer 1

Answer:

1. 2,4,8

Step-by-step explanation:

In continued proportion a : b = b : c; c is the third proportional to a and b

Answer 2

Answer:

2:4:8

Step-by-step explanation:

2:4:8 = 2:4::4:8 ⇒ 2*8 = 4*4 ∴ It is in continued proportion.

1:2:3 = 1:2::2:3 ⇒ 1*3 ≠ 2*2 ∴ It is not in continued proportion.

6:9:8 = 6:9::9:8 ⇒ 6*8 ≠ 9*9 ∴ It is not in continued proportion.

3:5:8 = 3:5::5:8 ⇒ 3*8 ≠ 5*5 ∴ It is not in continued proportion.

∴ 2:4:8 is the Answer.
