Find the value of x of an arithmetic progressions, Mathematics

Assignment Help:

Find the value of x if 2x + 1, x2 + x +1, 3x2 - 3x +3 are consecutive terms of an AP.

Ans: a² -a¹ = a³ -a²

⇒ x² + x + 1-2x - 1 = 3x² - 3x + 3- x²-x-1

x² - x = 2x² - 4x + 2

⇒ x² - 3x + 2 = 0

⇒ (x -1) (x - 2) = 0

⇒ x = 1 or x = 2
