What is the error in the number pattern 90,80,70,55,50,45
The error in the number pattern is the number 55. It does not fit the pattern of decreasing by 10 from each previous number.
To identify the error in the number pattern, let's analyze the given sequence: 90, 80, 70, 55, 50, 45.
Observing the pattern, we see that the sequence is decreasing by 10, then by 15, and then by 5 successively. This inconsistency indicates an error in the pattern.
The correct pattern should be as follows:
90, 80, 70, 60, 50, 40
In this updated pattern, the numbers decrease by 10 in each step.
