Which of the following numbers will replace the question marks (?) in the given series: 88, 78, 70, 64, 60, ?, ?

Question

Accepted Answer

Let's analyze the given series: 88, 78, 70, 64, 60, ?, ?

Step 1: Find the differences between consecutive terms:
78 - 88 = -10
70 - 78 = -8
64 - 70 = -6
60 - 64 = -4

Step 2: Observe the pattern in differences:
-10, -8, -6, -4
The differences are increasing by +2 each time (or decreasing in magnitude by 2).

Step 3: Continue the pattern for the next differences:
Next difference = -4 + 2 = -2
Then next difference = -2 + 2 = 0

Step 4: Calculate the next terms:
Next term = 60 + (-2) = 58
Following term = 58 + 0 = 58

Step 5: Verify options:
Option 4 suggests 58, 58 which matches our calculation.

Therefore, the correct answer is option 4: 58, 58.
