In the following question, select the missing number from the given series. 5, 20, 70, 210, 525, ?

A965

B1050

C840

D12820

Answer:

B. 1050

Read Explanation:


  • To find this answer, we need to identify the pattern in the sequence:

    • 5 × 4 = 20

    • 20 × 3.5 = 70

    • 70 × 3 = 210

    • 210 × 2.5 = 525

    • 525 × 2 = 1050

  • The pattern shows that each number is multiplied by a factor that decreases by 0.5 each time:

    • First multiplication: factor of 4

    • Second multiplication: factor of 3.5

    • Third multiplication: factor of 3

    • Fourth multiplication: factor of 2.5

    • Fifth multiplication: factor of 2
