Answer:

Z = 34

Step-by-step explanation:

From the series, we have that:

a = -2

a + d = 7

Hence, -2 + d = 7

∴ d = 7 + 2 = 9

a + 2d = X; a + 3d = Y and a + 4d = Z

-2 + 4(9) = Z

∴ Z = 36 - 2 = 34

Answer:

Solving the inequality $3x -2 < 4$ we get $\mathbf{x$

Option D is correct option.

Step-by-step explanation:

We need to solve the inequality $3x -2 < 4$ and find value of x

Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.

$3x -2 < 4$

Adding 2 on both sides

$3x -2+2 < 4+2\\3x < 6$

Now, we will divide 3 on both sides

$\frac{3x}{3}$

So, we get x < 2

Solving the inequality $3x -2 < 4$ we get $\mathbf{x$

Option D is correct option.
