Question

6. The value of x for which 2x, (x + 10) and (3x + 2) are
the three consecutive terms of an A.P., is
(a) 6
(b) 6
(c) 18
(d) –18​

Answer 1

Step-by-step explanation:

Consecutive terms of AP⇒2x,(x+10),(3x+2)

According to the properties

(x+10)−2x=(3x+2)−(x+10)

2(x+10)=2x+3x+2

4x+20=5x+2

x=18
