Correct Answer

C. (140)

Step 1

Concept

The subtracted values are (5,12,23), so \(a_4=140\). Exam tip: calculate the full value before subtracting.

Step 2

Why this answer is correct

The correct answer is C. (140). The subtracted values are (5,12,23), so \(a_4=140\). Exam tip: calculate the full value before subtracting.

Step 3

Exam Tip

घटने वाले मान (5,12,23) हैं इसलिए \(a_4=140\) है। घटाने से पहले पूरा मान निकालें।
