If x +2; 3x - 1; and 4x - 3 are the first three terms of an arithmentic progression?

Question

determine the value of x.
 write numerical values of the first three terms.
if the nth term is -41, calculate the value of n.

Answer

AP : (x+2); (3x-1); (4x-3); _______

Common Difference, d = (3x - 1) - (x + 2) = (4x - 3) - (3x - 1)

3x - 1 - x - 2 = 4x - 3 - 3x + 1

2x - 3 = x - 2

2x - x = -2 + 3

x = 1.
