Answer:

The fifth term is 8.

Step-by-step explanation:

Give n=5 in the general term

T 5=3(5)-7 = 15–7 =8

Another method

Tn = 3n - 7

T 1 = 3(1)-7 = -4

T 2 = 3(2) -7= -1

d= t 2 - t 1 = -1 -(-4)=3

a = -4 d=3

Tn = a + (n-1)d =

T 5 = a + (5–1)d = a +4 d = -4 +4(3)= 8

Solve the Inequality:<br> -0.5x > 4

nydimaria [60]

Answer:

x < -8

Step-by-step explanation:

Step 1: Divide both sides by -0.5 and flip the inequality sign.

$\frac{-0.5x}{-0.5} > \frac{4}{-0.5}$
$x < -8$

Therefore, the answer is x < -8.
