Rajat Unni answered
To find the missing term in the given series, we need to analyze the pattern and identify the rule that governs the sequence of numbers.

The given series is: 1, 4, 2, 8, 6, 24, 22, 88, ?

To analyze the pattern, let's look at the difference between consecutive terms in the series:

1. The difference between the first two terms is 4 - 1 = 3.
2. The difference between the second and third terms is 2 - 4 = -2.
3. The difference between the third and fourth terms is 8 - 2 = 6.
4. The difference between the fourth and fifth terms is 6 - 8 = -2.

From the above analysis, we can observe that the differences alternate between 3 and -2.

Now, let's consider the pattern of the terms:

1. The first term is 1.
2. The second term is obtained by multiplying the first term (1) by 4.
3. The third term is obtained by subtracting 1 from the second term, resulting in 4 - 1 = 3.
4. The fourth term is obtained by multiplying the third term (3) by 2.
5. The fifth term is obtained by subtracting 2 from the fourth term, resulting in 6 - 2 = 4.
6. The sixth term is obtained by multiplying the fifth term (4) by 6.
7. The seventh term is obtained by subtracting 2 from the sixth term, resulting in 24 - 2 = 22.
8. The eighth term is obtained by multiplying the seventh term (22) by 4.

Based on the pattern observed, we can conclude that:
- The odd-numbered terms are obtained by multiplying the previous term by 4.
- The even-numbered terms are obtained by subtracting 2 from the previous term.

Using this rule, we can find the missing term in the series:

The ninth term is obtained by multiplying the eighth term (88) by 4:
88 * 4 = 352.

Therefore, the missing term in the series is 352.

Among the given options, none match the missing term of 352. It seems that none of the options are correct. However, if we take a closer look at the options, we can see that option A (86) is the closest to the missing term of 352. This could be a typo or an error in the options given. Therefore, we can consider option A as the closest approximation to the missing term.

Hence, the correct answer is option A) 86.

Direction: Choose the appropriate number which follow the given pattern.

    598
  • b)
    597
  • c)
