• A) \(c _ { k } ( k + r ) ( k + r - 1 ) + c _ { k - 2 } = 0\)
• B) \(c _ { k } ( k + r ) ( k + r - 1 ) - c _ { k - 2 } = 0\)
• C) \(c _ { k } ( k + r + 1 ) ^ { 2 } - c _ { k - 2 } = 0\)
• D) \(c _ { k } ( k + r + 2 ) ( k + r + 1 ) + c _ { k - 2 } = 0\)
• E) \(c _ { k } ( k + r ) ( k + r + 1 ) - c _ { k - 2 } = 0\)
