समानांतर श्रेढ़ी \(35,31,27,23,\ldots\) का (n)वाँ पद कौन-सा है?

Correct Answer

B. \(a_n=39-4n\)

Step 1

Concept

The first term is (35) and the difference is (-4), so (a_n=35+(n-1)(-4)=39-4n). In a decreasing progression the common difference is negative.

Step 2

Why this answer is correct

The correct answer is B. \(a_n=39-4n\). The first term is (35) and the difference is (-4), so (a_n=35+(n-1)(-4)=39-4n). In a decreasing progression the common difference is negative.

Step 3

Exam Tip

पहला पद (35) और अंतर (-4) है इसलिए (a_n=35+(n-1)(-4)=39-4n)। घटती श्रेढ़ी में समान अंतर ऋणात्मक होता है।
