105-85=20
85-60=25
60-30=30
30-0=30
0-(-45)=45
-45-(-90)=45
if we replace 0 by -5 we get sequence like 20 25 30 35 40 45. that's y 0 is wrong ans.. am i correct
85-60=25

105-85 = 20.
85-60 = 25.
60-30 = 30.
30-0 = 30.
0-(-45 )= 45.
-45-(-90) = 45.
If we replace 0 by -5 we get sequence such as 20, 25, 30, 35, 40, 45.
85-60 = 25.
60-30 = 30.
30-0 = 30.
0-(-45 )= 45.
-45-(-90) = 45.
If we replace 0 by -5 we get sequence such as 20, 25, 30, 35, 40, 45.
