75, 65, 85, 55, 45, 85, 35, ....., What numbers should be next?
Ans:
a1 b1 c1 a2 b2 c2 a3 b3 C=fixed
75 65 85 55 45 85 35 (?) (?)
a1-a2=75-55=20 b1-b2=65-45=20 c1-c2=85-85=00
a2-a3=55-35=20 So,b2-b3=20=45-25* So, c2-c3=00=85-85*

Select 75, 65, 85.
55, 45, 85.
Know select 75-55=20.
65-45=20.
So we get 20.
Then.
Sub 20 from 55-20=35.
45-20=25.
Here 85 is common.
Answer is 35, 25, 85.
