Correct Answer

C. (6)

Step 1

Concept

For three consecutive terms, (2(2x+1)=(x-3)+(4x-1)), giving (x=6). The middle term is the average of the two surrounding terms.

Step 2

Why this answer is correct

The correct answer is C. (6). For three consecutive terms, (2(2x+1)=(x-3)+(4x-1)), giving (x=6). The middle term is the average of the two surrounding terms.

Step 3

Exam Tip

लगातार तीन पदों में (2(2x+1)=(x-3)+(4x-1)), इससे (x=6) मिलता है। बीच वाला पद दोनों ओर के पदों का औसत होता है।
