In the following question, select the missing number from the given series.
15, 42, 164, 815, ?
The pattern is:
15
15 × 3 - 3 = 42;
42 × 4 - 4 = 164
164 × 5 - 5 = 815;
815 × 6 - 6 = 4884
Hence, the answer is '4884'.In the following question, select the missing number from the given series.

Similarly, Hygrometer is an instrument used to measure Humidity
Hence, ‘Humidity’ is for ‘Hygrometer’Concept:
Different sigma levels of quality would lead to the following number of defects.
Important Points:
Four sigma and six sigma levels of performance both have an error free rate over 99% of the time. However, the large volume of applications in this example makes all of the difference. With numbers this big, it turned out that the four-sigma process made 18,710 more errors than the six sigma process.
The correct answer is Bundi, Udaipur, Pratapgarh and Banswara
Key Points

Additional Information
In alphabet group there is difference of five except ‘QU’
E + 5 → J
O + 5 → T
Q + 4 → U
M + 5 → R
Hence, ‘QU’ does not belong to the group.
