Answer:
Pattern: The pattern to follow is to subtract 1 from the previous number and then multiply it by 2.
Explanation:
To find the appropriate number that follows the given pattern, let's analyze the options one by one.
a) 512: If we apply the pattern to this number, we subtract 1, which gives us 511. Then, if we multiply 511 by 2, we get 1022. Therefore, option 'a' does not follow the given pattern.
b) 511: If we subtract 1 from 511, we get 510. Multiplying 510 by 2 gives us 1020. Therefore, option 'b' follows the given pattern.
c) 513: Subtracting 1 from 513 gives us 512. Multiplying 512 by 2 results in 1024. Therefore, option 'c' does not follow the given pattern.
d) 514: If we subtract 1 from 514, we get 513. Multiplying 513 by 2 gives us 1026. Therefore, option 'd' does not follow the given pattern.
Conclusion:
Based on the given pattern, the appropriate number that follows the pattern is 511, which is option 'b'.
