Correct Answer

A. (-3)

Step 1

Concept

Here (a=15) and (d=-3), so (a_7=15+6(-3)=-3). In a decreasing progression, terms may go below zero.

Step 2

Why this answer is correct

The correct answer is A. (-3). Here (a=15) and (d=-3), so (a_7=15+6(-3)=-3). In a decreasing progression, terms may go below zero.

Step 3

Exam Tip

यहाँ (a=15) और (d=-3), इसलिए (a_7=15+6(-3)=-3)। घटती श्रेढ़ी में पद शून्य से नीचे भी जा सकते हैं।
