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
First off, remember PEMDAS. Then replace the variables with the values.
3(2x3)^2
First distribute the exponent to the value on the inside.
3(4x9)
Then multiply the 4 and 9.
3(36)
After that just distribute the 3.
3x36 = 108.
