Question

The same number is added to each term in a pattern to get the value of the next term. Below are the fourth, fifth and sixth terms in the pattern. …89, 93, 97,…
The first, second and third terms in the pattern is ___________

  1. 76, 79, 81    
  2. 77, 81, 84    
  3. 77, 81, 85    
  4. 78, 80, 85    

hintHint:

In the given question, we are required to find the number with which each of the numbers is added to get a pattern. We need to find the first, second and the third term of the series.

The correct answer is: 77, 81, 85


    Step by step solution:
    89 + 4 = 93
    93 + 4 = 97
    The series is an increasing progression with the common difference 4.
    Thus, the term previous to 89, i.e., the third term = 89 - 4 = 85
    the second term = 85 - 4 = 81
    the first term = 81 - 4 = 77
    Thus, the first, second and the third term in the series is 77, 81, 85.
    Hence, option(c) is the correct option.
