Find the wrong number in the following number series.7, 9, 11, 15, 21,...
The wrong number in the given number series is 35.
Explanation:
In the given number series, we can observe the following pattern:
- The first number, 7, is increased by 2 to get the second number, 9.
- The second number, 9, is increased by 2 to get the third number, 11.
- The third number, 11, is increased by 4 to get the fourth number, 15.
- The fourth number, 15, is increased by 6 to get the fifth number, 21.
However, the pattern breaks at the sixth number, which is 35. Following the same pattern, we would expect the sixth number to be 27 (21 + 6). Therefore, the number 35 is the wrong number in the series.
Let's analyze the other options:
a) 7: This is the first number in the series, and it follows the pattern.
b) 9: This is the second number in the series, and it also follows the pattern.
c) 11: This is the third number in the series, and it also follows the pattern.
d) 35: This is the sixth number in the series, but it does not follow the pattern. Therefore, this is the wrong number.
Conclusion:
The wrong number in the given number series is 35.
