Analyzing +4 | -1

\frac{1}{{b - c}},\;\frac{1}{{c - a}},\;\frac{1}{{a - b}}

be consecutive terms of an AP, then

{\left( {b - c} \right)^2},\;{\left( {c - a} \right)^2},\;{\left( {a - b} \right)^2}

will be in

View answer and explanation

Correct option: B

Option B (AP) is correct because if

\frac{1}{{b - c}}, \frac{1}{{c - a}}, \frac{1}{{a - b}}

are in A.P., then

{\left( {b - c} \right)^2},{\left( {c - a} \right)^2},{\left( {a - b} \right)^2}

are also in A.P.
