205 is the missing number.

Step-by-step explanation:

Given, a question based on finding missing number.

To solve these kind of questions, we need to find the process involved in the given options such as addition, subtraction, multiplication, division, squares and cubes and so on to find out the correct answer.

Here, the logic is :-

10 × 0.5 + 10 = 15

15 × 1 + 20 = 35

35 × 1.5 + 30 = 82.5

82.5 × 2 + 40 = 205

205 × 2.5 + 50 = 562.5

Hence, 205 is the missing number of the given series.
