Q. Type the missing number in this sequence:102, 97, 92, 87, _, 77, 72
Identify Pattern: We need to identify the pattern in the sequence. By looking at the sequence, we can see that each number is 5 less than the previous number.Calculation: 97−102=−5, 92−97=−5, 87−92=−5
Find Missing Number: To find the missing number, we subtract 5 from the last known number in the sequence before the missing number.Calculation: 87−5=82
Check Result: We can check our result by adding 5 to the missing number to see if we get the next number in the sequence.Calculation: 82+5=87 (which is the number before the missing number) and 82+5=87 (which is the number after the missing number)
