Answer:
a=-4000m+39000
Step-by-step explanation:
From the given table, we can see that the difference between any consecutive altitude is 4000 ft.
31000 - 35000 = -4000
27000- 31000 = -4000
23000-27000 = -4000
Hence, it represents an arithmetic sequence with a = 3500 and d = -4000
The general term of an arithmetic sequence is given by
[tex]a_n=a+(n-1)d\\\\a=35000+(m-1)(-4000)\\\\a=35000-4000m+4000\\\\a=-4000m+39000[/tex]
