Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Analyze the subtraction pattern between consecutive terms.
Step 2: Analysis
$100 - 97 = 3$
$97 - 91 = 6$
$91 - 82 = 9$
The terms are decreasing by multiples of 3.
Step 3: Calculation
Next subtraction should be 12.
$82 - 12 = 70$.
Step 4: Verification
$70 - 15 = 55$ (matches the sequence). Final Answer: (1)
