Question

If x + 1, 3x and 4 x + 2 are in AP find x

Answer 1

Answer:

as they are in AP so common difference will be same

3x - x - 1 = 4x + 2 - 3x

3x + 3x - 4x - x = 2 + 1

x = 3

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Let x+1 be a

3x be b

and, 4x+2 be c

we know that if a,b,c are in AP then

b is arithmetic mean of a and c

Now put value of a,b and c in b=(a+c)÷2

You will get x=3 and that the answer I hope so
