Correct Answer

A. (-6)

Step 1

Concept

Here (a=60) and (d=-6), so (a_{12}=60+11(-6)=-6). In a decreasing progression, terms can become negative.

Step 2

Why this answer is correct

The correct answer is A. (-6). Here (a=60) and (d=-6), so (a_{12}=60+11(-6)=-6). In a decreasing progression, terms can become negative.

Step 3

Exam Tip

यहाँ (a=60) और (d=-6), इसलिए (a_{12}=60+11(-6)=-6)। घटती श्रेढ़ी में पद ऋणात्मक भी हो सकते हैं।
