Question

If 6 - a, x and 6 + a are in A.P, then the
value of x is
a) 6 b)-6 c) 12 d)-12​

Answer 1

Answer:6

Step-by-step explanation:

a = 6-a

a+d = x

a+2d= 6+a

2d = 6+a - 6+a

d = a

x = 6+a-a = 6

Answer 2

Answer:

In an AP Cmmon difference (d) = a2 - a1 = a4 - a3 = a6 - a5 = a8 - a7, .............

=> x - (6 - a) = 6 + a - x

=> x - 6 + a = 6+ a - x

=> 2x = 12

=> x = 6
