(n - 2)180 = sum of angles (six sides)
(6 - 2)180 = y
(4) 180 = y
720= y
115+110+x+25+x-30+x+x = 720
4x + 220 = 720
4x = 720 - 220
4x = 500
x = 500/4
x = 125
The answer should be approximately 0.4

Answer:

Step-by-step explanation:
Here, you can see every consecutive term is divided by 2. I think that's pretty obvious looking at it, but you can work it out like this if you'd like to. Divide each consecutive term by the one before it:

Each term is multiplied by 1/2 over the last, or divided by 2. In this case actually, we do want it in the form of "multiplied by 1/2", as the recursive equation is:

where x is the factor. Here, we're multiplying by x, so we want "multiplied by 1/2" as described above. x is 1/2, so you can write the equation:

You can simply interpret this as "each term is 1/2 of the term before it"
