Answers
Answer:
27 ? Is it 27. Because I am am confused. Can you please tell the pattern I will tell the answer
Given:
A sequence 3, 12, 27, 48, 9, 24, 45, 72, 15, 36, ___, 96.
To Find:
The missing number in the mentioned series.
Solution:
The given problem can be solved by developing a common logic among the given numbers.
- The second number in the sequence is obtained using the following logic,
=> 12 = 3 + 9. ( First term + 9).
- The third number in the sequence is obtained using the following logic,
=> 27 = 12 + 15. ( Second term + 9 + 6).
- The fourth number in the sequence is obtained using the following logic,
=> 48 = 27 + 21. ( Third term + 9 + 6 + 6).
- The fifth term is obtained using the following logic,
=> 9 = 3 + 6. ( First term + 6).
- The sixth number in the sequence is obtained using the following logic,
=> 24 = 9 + 15. ( Fifth term + 15).
- The seventh number in the sequence is obtained using the following logic,
=> 45 = 24 + 21. ( Sixth term + 15 + 6).
- The eighth number in the sequence is obtained using the following logic,
=> 72 = 45 + 27. ( Seventh term + 15 + 6 + 6).
- The Nineth number in the sequence is obtained using the following logic,
=> 15= 3 + 12 . ( First term + 12).
From the above calculations, the following are the common patterns in the sequence.
- The sequence increases 3 times and then has a decrease in the value. The decreases value depends on the first number of the sequence.
- Each number is obtained from the previous numbers with some common addition.
- The number 36 is obtained by using the logic,
=> 36 = 15 + 21.
- The next term in the series can be obtained using the same logic. Hence,
=> New term = 36 +27,
=> New term = 63.
Therefore, the missing number in the sequence is 63.
