The followed pattern is:
First number = 1
(1 × 3) – 2 = 1
(1 × 6) – 4 = 2
(2 × 9) – 6 = 12
(12 × 12) – 8 = 136
Hence, 136 is the missing term.

A series is given with one term missing. Select the correct alternativ...
Given series: 1, 1, 2, 12, ?
The given series does not appear to follow a simple arithmetic or geometric pattern. However, we can analyze the given terms to identify a pattern and find the missing term.
Step 1: Analyzing the given terms
- The first term is 1.
- The second term is also 1.
- The third term is 2, which is the product of the first two terms (1 * 1).
- The fourth term is 12, which is the product of the second and third terms (1 * 2 * 6).
Step 2: Identifying the pattern
From the analysis of the given terms, we can observe that each term is obtained by multiplying the previous terms in a specific pattern. The pattern can be described as follows:
- The first term is 1.
- The second term is also 1.
- The nth term is the product of the previous n-1 terms.
Step 3: Applying the pattern to find the missing term
We can apply the identified pattern to find the missing term. Let's use the given terms to calculate the missing term.
- The first term is 1.
- The second term is also 1.
- The third term is the product of the first two terms (1 * 1) = 1.
- The fourth term is the product of the second and third terms (1 * 1 * 2) = 2.
- The fifth term is the product of the third and fourth terms (1 * 1 * 2 * 12) = 24.
Therefore, the missing term in the given series is 24.
Conclusion:
The missing term in the series 1, 1, 2, 12, ? is 24.
