Answer:
Third number is 12
Step-by-step explanation:
Let
be common difference &
be the third number. Set up the following equations:

Solve the simultaneous equation for x-term:

Let’s make sure that we get accurately answer. Substitute x = 12 in any equations which I’ll choose (1):

Now add each terms with common difference as 7:
-2+7 = 5
5+7 = 12
12+7 = 19
19+7 = 26
So our pattern is -2, <u>5</u>, <u>12</u>, <u>19</u>, 26. Since the question only asks for third number then the answer is 12

I'm sorry I don't know but can you please see if you know how to do any of my last few questions no one is answering and I'm freaking out
A line segment is a line with two end points. Hope this helped! Good luck! :)
You just have to be patient and wait, love. I’m sure people try to answer asap.
Use trigonometry.
sin x = opposite ÷ hypotenuse
sin x = 7/9
Take the arcsin on both sides.
arcsin(sin x) = arcsin(7/9)
x = 51.057558731
Rounding to the nearest whole number means to round to the ones place.
Answer: x = 51 degrees
