In the following question, select the missing number from the given series.
85, 84, 92, 83, 147, ?

Correct option is C

Given: 85, 84, 92, 83, 147, ?
Logic: Subtract the square of odd numbers and add the cube of even numbers alternately.
First Step: Starting with 85, subtract the square of 1:
85−1=84.
Second Step: Add the cube of 2:
84+8=92.
Third Step: Subtract the square of 3:
92−9=83.
Fourth Step: Add the cube of 4:
83+64=147.
Fifth Step: Subtract the square of 5:
147−25=122.
So, the sixth number is 122.
The missing number in the series is 122.
Correct Answer: (c) 122
