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

Answer:
Step-by-step explanation:
we know,
The Angle Addition Postulate states that: If a point lies in the interior of an angle, then the postulate describes that putting two angles side by side with their vertices together creates a new angle whose measure equals the sum of the measures of the two original angles.
Here, W is the internal point.
The two angles are UVW and WVX.
Now, by the angle addition postulate,
UVX is equal to the sum of UVW and WVX.
Hence, the reason is-
