Find the values of x in the Arithmetic series 3x+1,5x-1,5x+1,......

2

NA

Solution;

Formula; If a,b and c are in arithmetic series, then

2b = a + c

Here, a = 3x + 1

b = 5x - 1

c = 5x + 1

So, 2 (5x - 1) = 3x + 1 + 5x + 1

10x - 2 = 8x + 2

10x - 8x = 2 + 2

2x = 4

x = 4/2

x = 2

So,the correct option is A). 2
