Let’s find X first! Let’s use the vertical angle theorem to move 67 over. Now 3x+7=67 let’s solve. We get X=20
Let’s find y!
We know that 67 and y will add up to 180 because straight lines are 180 degrees. Let’s do y+67=180 let’s solve! We get y=113
Answer:
4n-1
Step-by-step explanation:
The difference in the numbers is 4 so the coefficient must be 4 for the nth term meaning
4n
11 is the third term however we need to find the first so..
11=3rd term
-4
7=2nd term
-4
3=1st term
now we need to minus 4 from 3 which is -1 (3-4)
meaning the answer put together will be 4n-1
