All numbers/15 is an in integer excepr 85. So 85 must also be considered an answer.
105/15 = 7,
85/15 = 5.6,
60/15 = 4,
30/15 = 2,
0/15 = 0,
-45/15 = -3,
-90/16 = -9.
Find odd one out 105, 85, 60, 30, 0, -45, -90.
105/15 = 7,
85/15 = 5.6,
60/15 = 4,
30/15 = 2,
0/15 = 0,
-45/15 = -3,
-90/16 = -9.
Find odd one out 105, 85, 60, 30, 0, -45, -90.

@B D Vekaria.
b) 50, 51, 47, 56, 42, 65, 29.
Answer is 42 because
+1, -4, +9, -16, +25, -36 ------> 1^2, 2^2, 3^2, 4^2, 5^2, 6^2.
But we are getting 1, -4, +9, -14.

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
60-30=30
30-0=30
0-(-45)=45
-45-(-90)=45

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.

@D B Vekaria.
The wrong answer is 20.
3-1=2, 6-3=3, 1-61=5, 20-11=9, 9-20=11, 70-39=31.
2, 3, 5, 11, 31 are prime numbers except 9.
The wrong answer is 20.
3-1=2, 6-3=3, 1-61=5, 20-11=9, 9-20=11, 70-39=31.
2, 3, 5, 11, 31 are prime numbers except 9.

85 is also a probable answer to this question.
Because each of the given numbers in the series except 85 is divisible by 3.

I agree @Bhavana.
We have to select the odd one out so yeah except 85 all others are divisible by 3 and 15.
