**Answer:**

**Step-by-step explanation:**

letter H is 324, they are multiplying by 3 each time

letter k is multiplying by 1.5 each time so your next term is 10.125

i cant fully see the other, but i hope this helps!!!

x=4

**Step-by-step explanation:**

4(-6+5x)=24+8x

open the bracket

-24+20x=24+8x

collect like terms

20x-8x=24+24

12x=48

divide both sides by 12

12x/12 = 48/12

x= 4

-7+7n=2(-7+7n)

open the brackets

-7+7n=-14+14n

collect like terms

14n-7n=-14+7

7n=-7

divide through by 7

n=-1

3,6,9,12,15

That’s the answer

**Answer:**

<h2>0</h2>

**Step-by-step explanation:**

Given the expression after 4 has been subtracted from both sides as

1/2 x = - 1/2 x, the original expression will be gotten by adding back 4 to both sides of the resulting expression as shown;

1/2 x + 4 = - 1/2 x + 4

x/2 + 4 = -x/2 + 4

Find the LCM of both equation;

(x+8)/2 = (-x+8)/2

Multip<u>l</u>ying both sides by 2 will give;

x+8 = -x+8

Collecting the like terms;

x+x = 8-8

2x = 0

x = 0/2

**x = 0**

**Hence, the value of x is 0**
