@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.

@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.

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

I think 85 is also a correct answer because except 85 all are divisible by 3.

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.
