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 identify the wrong number in the sequence, let us analyze the mathematical relationship and pattern between consecutive terms:
32, 16, 16, 32, 128, 975, 16384
Let us look at how each term is obtained from the preceding term:
First term to second term:
Second term to third term:
Third term to fourth term:
Fourth term to fifth term:
Notice the pattern in the multipliers used: 0.5, 1, 2, 4. Each multiplier is double the previous multiplier (, , ).
Following this pattern, the next multiplier should be:
Applying this multiplier to the fifth term (128):
To confirm the pattern for the final term, the next multiplier after 8 should be:
Multiplying 1024 by 16 gives:
This matches the final number in the sequence (16384). Therefore, the number 975 is incorrect and should be replaced by 1024.
