The value of x is 10 and the nth term of the sequence is 24n-17 with the 1st three terms being 7, 31, 55

(3x + 1) - (x - 3) = (6x - 5) - (3x + 1) 2x + 4 = 3x - 6 10 = x

The sequence needs a common difference. 6x - 5 - (3x + 1) = 3x + 1 - (x - 3) 3x - 6 = 2x + 4 x = 10

2x+2=x-3+6x+5 2x-x-6x=0 -5x=0 x=0

(x - 3), (3x + 1), (6x - 5) are consecutive terms of an arithmetic sequence. (3x + 1) - (x - 3) = (6x - 5) - (3x + 1) 2x + 4 = 3x - 6 x = 10 The consecutive terms of the arithmetic sequence are 7, 31 and 55.
