29,48,67,86,x in this series what is the value of x
Answers
105
This problem is a 'terms in series' problem where every term is related to the previous term in a fix pattern and the pattern remains constant for each progression.
Here, the numbers in units place are descending. 9,8,7,6 and so on while the numbers in the tens place of each successive term is and increasing even number. 2,4,6,8 and so on.
Thus, the next digit in units place = 5 and next digit in tens place = 10
∴ next term = 105
Given:
A series of numbers 29,48,67,86,x
To Find:
The value of x in the series is?
Solution:
The given problem can be solved by developing a common logic between every term.
1. The given series is 29,48,67,86,x
2. The second term in the series is obtained as,
=> Second term = 48 = 29 + 19,
3. The third term of the series is obtained as,
=>Third term = 67 = 48 + 19,
4. The fourth term of the series is obtained as,
=>Fourth term = 86 = 67 + 19,
5. The fifth term of the series can be obtained using similar logic,
=> Fifth term = (previous term + 19) = 86 + 19 = 105.
=> Fifth term = x = 105.
Therefore, the next number in the series is 105.
