If (2x-3, x+4, 3x-1) are consecutive terms of an arithmetic progression, what is the value of (x)?
Answer and explanation
Correct answer: (3)
Twice the middle term equals the sum of the other two terms, so (2(x+4)=(2x-3)+(3x-1)) gives (x=3). For three consecutive terms, the middle-term rule is fast.
