1, 12, 14, ?, 66, 142Choices:- 40 50 38 42

To find the missing number in the sequence 1, 12, 14, ?, 66, 142, we need to identify the pattern or rule that governs the sequence.

Looking at the given numbers, we can observe that each number is obtained by adding a certain value to the previous number.

From 1 to 12, we add 11 (1 + 11 = 12). From 12 to 14, we add 2 (12 + 2 = 14). From 14 to the missing number, we add 24 (14 + 24 = ?). From the missing number to 66, we add 52 (? + 52 = 66). From 66 to 142, we add 76 (66 + 76 = 142).

Therefore, to find the missing number, we add 24 to 14.

14 + 24 = 38.

So, the missing number in the sequence is 38.

Among the given choices, the correct answer is 38.
