Find the value of x for which the numbers (5x + 2), (4x – 1) and (x + 2) are in AP. |
Answer» Given: (5x + 2), (4x – 1) and (x + 2) are terms in AP. So, d = (4x – 1) – (5x + 2) = (x + 2) – (4x – 1) 2(4x – 1) = (x + 2) + (5x + 2) 8x – 2 = 6x + 2 + 2 8x – 2 = 6x + 4 8x – 6x = 4 + 2 or x = 3 The value of x is 3. |
