1. Angle A is not 105degrees. As you can see on the horizontal line that it lies on, it's under 90degrees(acute). The angle aside from it is over 90degrees(obtuse).
2.Angle B is in fact not 75degrees.. By looking at the angle it's obtuse, over 90 degrees, so it can't be 75degrees.
Answer:
Option (2)
Step-by-step explanation:
In an arithmetic progression,

First term of the progression,
a = 
Common difference 'd' = 
Recursive formula for the sequence,
a = 

By applying these rules in the recursive formula,


Common difference 'd' = 
Therefore, Option (2) will be the answer.
