For the sequence provided below, a single number does not follow the correct pattern. Determine the wrong number.
32, 16, 16, 32, 128, 975, 16384
Correct Answer :
975
Solution :
Correct Answer: 975
To find the wrong number in the given sequence, let us analyze the mathematical relation between each consecutive term:
32, 16, 16, 32, 128, 975, 16384
Let us determine the multiplier used to obtain each subsequent term from the previous one:
First term to second term:
Second term to third term:
Third term to fourth term:
Fourth term to fifth term:
Notice the pattern of multipliers: 0.5, 1, 2, 4. Each multiplier is multiplied by 2 (doubled) to get the next multiplier:
Following this pattern, the next multiplier must be:
Applying this multiplier to the fifth term (128):
To verify, the subsequent term using the next multiplier () should be:
This perfectly matches the last number in the given sequence.
Therefore, the number 975 is incorrect and should be replaced by 1024.
