Directions (1-5): In the following series find the term which is place...
Ans - 20
[5*2-2=8], [8*3-2=22], [22*2-2=42], [42*3-2=124],[124*2-2=246], [246*3-2=736]
So 3rd term should be 22 instead of 20

Directions (1-5): In the following series find the term which is place...
Incorrect term: 20
Explanation:
The given series is: 5, 8, 20, 42, 124, 246, 736.
To find the incorrect term, we need to identify the pattern or rule followed by the series.
Observing the given series, we can see that each term is obtained by applying a specific mathematical operation to the previous term.
Let's analyze the series term by term:
1st term: 5
2nd term: 8
The difference between the 2nd term and the 1st term is 8 - 5 = 3.
3rd term: 20
The difference between the 3rd term and the 2nd term is 20 - 8 = 12.
4th term: 42
The difference between the 4th term and the 3rd term is 42 - 20 = 22.
5th term: 124
The difference between the 5th term and the 4th term is 124 - 42 = 82.
6th term: 246
The difference between the 6th term and the 5th term is 246 - 124 = 122.
From the above analysis, it is clear that the differences between consecutive terms are increasing by 9 each time.
Therefore, the next difference should be 122 + 9 = 131.
7th term: 736
To obtain the 7th term, we need to add the next difference to the 6th term: 246 + 131 = 377.
Therefore, the correct series is: 5, 8, 20, 42, 124, 246, 377.
Hence, the term 20 is placed incorrectly in the given series.

The difference between the 5th term and the 4th term is 124 - 42 = 82.
