Q. Type the missing number in this sequence:13,11,____,7,5
Identify Pattern: Identify the pattern in the sequence.We notice that the sequence is decreasing. To find the pattern, we look at the difference between the consecutive numbers that are given.13−11=2So, it seems that the sequence decreases by 2 each time.
Apply Pattern: Apply the pattern to find the missing number. If we subtract 2 from 11 (the number before the missing number), we should get the missing number. 11−2=9
Verify Continuation: Verify the pattern continues correctly after the missing number.Now, we add 2 to the missing number to see if we get the next number in the sequence.9+2=11But we need to check if this result matches the number after the missing number in the sequence, which is 7.Since 11 does not equal 7, this indicates that we have made a mistake.
