Answer :-

def ser(    a  , b ) :
    d = int ( ( b - a ) / 3 )
    print("Series = " , a , a + d , a + 2*d , b )

first = int(input("Enter first Term = "))
last = int(input("Enter last Term = "))

ser(first , last )

Output :-

Enter first Term = 1
Enter last Term = 7
Series =  1 3 5 7
>>> 

Enter first Term = 7
Enter last Term = 1
Series =  7 5 3 1
>>> 

Enter first Term = 2
Enter last Term = 8
Series =  2 4 6 8
>>> 

Enter first Term = 100
Enter last Term = 60
Series =  100 87 74 60
>>>
