Number series – constant decrement of 121 (11^2): 796, 675, 554, 433, ? Continue subtracting 121 each time.

Introduction / Context:
A fixed subtraction pattern, especially by a notable square like 121 (=11^2), is common in reasoning sets. Confirm the fixed drop and extend once more.

Given Data / Assumptions:

• 796→675 (−121), 675→554 (−121), 554→433 (−121).

Concept / Approach:
Apply the same subtraction again.

Step-by-Step Solution:

Verification / Alternative check:
Adding back 121 from 312 returns to 433, confirming consistency.

Why Other Options Are Wrong:

Common Pitfalls:
Searching for changing differences where a single constant drop fits perfectly.

Final Answer:
312
