Show answer & explanation
Correct answer: A
To find the next number in the series 100, 92, 85, 79, 74, ___, we need to identify the pattern of differences between consecutive terms.
Step-by-Step Analysis
Examine the transitions:
100 - 92 = 8
92 - 85 = 7
85 - 79 = 6
79 - 74 = 5
Identify the pattern:
The difference between the numbers is decreasing by 1 each time (8, 7, 6, 5).
Following this logic, the next difference must be 4.
Calculate the next term:
74 - 4 = 70.
