No it is not, there is no common difference. <span />
we know that
In a parallelogram opposite angles are congruent and consecutive angles are supplementary.
So
m∠O=m∠M
m∠L=m∠N
m∠O+m∠L=![180](https://tex.z-dn.net/?f=%20180%20)
Step ![1](https://tex.z-dn.net/?f=%201%20)
Find the value of x
![(x+20)+(2x+10)=180\\ 3x+30=180\\ 3x=180-30\\ x=\frac{150}{3} \\ \\ x=50\ degrees](https://tex.z-dn.net/?f=%20%28x%2B20%29%2B%282x%2B10%29%3D180%5C%5C%203x%2B30%3D180%5C%5C%203x%3D180-30%5C%5C%20x%3D%5Cfrac%7B150%7D%7B3%7D%20%5C%5C%20%5C%5C%20x%3D50%5C%20degrees%20)
Step ![2](https://tex.z-dn.net/?f=%202%20)
Find the value of angle L
m∠L![=(2x+10)](https://tex.z-dn.net/?f=%20%3D%282x%2B10%29%20)
m∠L![=(2*50+10)](https://tex.z-dn.net/?f=%20%3D%282%2A50%2B10%29%20)
m∠L![=110\ degrees](https://tex.z-dn.net/?f=%20%3D110%5C%20degrees%20)
Remember that
m∠N=m∠L
m∠N=![110\ degrees](https://tex.z-dn.net/?f=%20110%5C%20degrees%20)
therefore
the answer is
the measure of the angle N is equal to ![110\ degrees](https://tex.z-dn.net/?f=%20110%5C%20degrees%20)
