Correct Answer

B. (78)

Step 1

Concept

(a_5=4\(5^2\)-3(5)+2=87) and (a_2=4\(2^2\)-3(2)+2=9). Therefore the difference is (87-9=78).

Step 2

Why this answer is correct

The correct answer is B. (78). (a_5=4\(5^2\)-3(5)+2=87) and (a_2=4\(2^2\)-3(2)+2=9). Therefore the difference is (87-9=78).

Step 3

Exam Tip

(a_5=4\(5^2\)-3(5)+2=87) और (a_2=4\(2^2\)-3(2)+2=9) है। इसलिए अंतर (87-9=78) है।
