Correct Answer

C. (66)

Step 1

Concept

The increase over five gaps is (30), so (d=6) and (a_{12}=48+3(6)=66). First find (d), then move forward.

Step 2

Why this answer is correct

The correct answer is C. (66). The increase over five gaps is (30), so (d=6) and (a_{12}=48+3(6)=66). First find (d), then move forward.

Step 3

Exam Tip

पाँच अंतरों में वृद्धि (30) है, इसलिए (d=6) और (a_{12}=48+3(6)=66)। पहले (d) निकालें फिर आगे बढ़ें।
