The actual question is not visible
1). Am I seated comfortably, with plenty of light on my paper ?
2). Is my pencil sharp ?
Answer:
Neither.
Step-by-step explanation:
13 - 1 = 12 and 19 - 13 = 6 - no common difference so its not Arithmetic.
13/1 = 13 and 19/13 = 1.46 - no common ratio so its not Geometric.
The answer is x=6. This is because 6+4 equals 10
