Answer:1
Step-by-step explanation:for the taxi fare for initial kilometre ,it will be 15 after that 8 will be added for further kilometres so it will form an AP :15,15+8,15+8+8,15+8+8+8+......
With the first term of AP=15 and the common difference=8
For 2nd case ,suppose there is x amount of air,if ¼ of air will removed, remaining air will be 3x/4 ,now for further removal , remaining air will be 9x/16 which will form an geometric progression not Arithmetic progression
