Select the number from among the given options that can replace the question mark (?) in the following series.
14,19,34,79,?

  1. A
    186
  2. B
    144
  3. C
    214
  4. D
    227

Solution & Step-by-step Explanation

Let's find the difference between consecutive terms:
19−14=5

34−19=15

79−34=45

Notice the pattern in the differences:

5×3=15

15×3=45

The differences are being multiplied by 3 at each step. Following this pattern, the next difference should be:

45×3=135
Therefore, the missing number is:

79+135=214
