Number Series:
The given number series is: 85, 89, 86, 94, ?, 100, 91, 107, 95
Observations:
To find the missing number in the series, let's analyze the given numbers and look for any patterns or relationships between them.
- The series seems to be alternating between increasing and decreasing numbers.
- The first number, 85, is followed by an increase of 4 to get 89.
- The second number, 89, is followed by a decrease of 3 to get 86.
- The third number, 86, is followed by an increase of 8 to get 94.
- The fourth number, 94, is followed by a decrease of ? to get the missing number.
- The missing number is followed by an increase of 9 to get 100.
- The sixth number, 100, is followed by a decrease of 9 to get 91.
- The seventh number, 91, is followed by an increase of 16 to get 107.
- The eighth number, 107, is followed by a decrease of 12 to get 95.
Pattern:
Based on the observations, the pattern in the series can be described as follows:
- Add 4, then subtract 3, then add 8, then subtract ?, then add 9, then subtract 9, then add 16, then subtract 12.
Calculation:
To find the missing number, we need to determine the value to subtract from 94 in order to obtain the next number, which is 100.
94 - ? = 100
? = 94 - 100
? = -6
Conclusion:
The missing number in the series is -6. Therefore, the number that should come in the place of the question mark is 85, 89, 86, 94, -6, 100, 91, 107, 95.
