Missing Number in the First Sequence: 7 8 6
To find the missing number in the given sequence 7 8 6, we need to observe the pattern or logic behind the given numbers. Let's analyze the sequence:
- The first number, 7, is followed by 8.
- The second number, 8, is followed by 6.
From this analysis, we can see that each number is being replaced by its adjacent number in reverse order. Therefore, the missing number can be found by replacing the second number, 8, with its adjacent number, which is 6.
So, the missing number in the first sequence is 6.
Missing Number in the Second Sequence: 4 9 5
Now, let's analyze the second sequence:
- The first number, 4, is followed by 9.
- The second number, 9, is followed by 5.
Similar to the first sequence, each number is being replaced by its adjacent number in reverse order. Therefore, the missing number can be found by replacing the second number, 9, with its adjacent number, which is 5.
So, the missing number in the second sequence is 5.
Missing Number in the Third Sequence: 3 2 ?
Moving on to the third sequence, let's analyze it:
- The first number, 3, is followed by 2.
- The second number, 2, is followed by the missing number.
Following the pattern observed in the previous sequences, each number is being replaced by its adjacent number in reverse order. Therefore, the missing number can be found by replacing the second number, 2, with its adjacent number, which is 1.
So, the missing number in the third sequence is 1.
Missing Number in the Fourth Sequence: 25 70 29
Finally, let's analyze the fourth sequence:
- The first number, 25, is followed by 70.
- The second number, 70, is followed by 29.
Unlike the previous sequences, there is no clear pattern of replacing each number with its adjacent number in reverse order. Therefore, we need to analyze the numbers further to identify the logic behind them.
By observing the difference between the first and second numbers, we can see that it is 70 - 25 = 45. Similarly, the difference between the second and third numbers is 70 - 29 = 41.
Based on this pattern, we can find the missing number by subtracting 41 from the second number, 70.
So, the missing number in the fourth sequence is 29 - 41 = -12.
However, none of the given options (-12) match this result. Therefore, there may be an error in the options provided, or the sequence may not follow a clear pattern.
