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