Answer 1

I think B is your answer

But I am not sure

Answer 2

Answer:

558.5 is the wrong term

Step-by-step explanation:

The pattern of the following number series is:

⇒ 3,

⇒ 6 = 3 × 1.5 + 1.5 × 1

⇒ 16 = 6 × 2 + 2 × 2

⇒ 47.5 = 16 × 2.5 + 2.5 × 3

⇒ 154.5 = 47.5 × 3 + 3 × 4

⇒ 558.25 = 154.5 × 3.5 + 3.5 × 5

Hence the wrong term of the series is 558.5, it should be 558.25

⇒  2257 = 558.25 × 4 + 4 × 6
