Full solution

Q. Type the missing number in this sequence:\newline55, 2525, _\_, 625625, 3,1253,125, 15,62515,625
  1. Identify Pattern: We observe the given sequence to identify a pattern: 5, 25, _____, 625, 3,125, 15,625. By looking at the numbers, we can see that each number is a multiple of the previous one. To confirm the pattern, we can divide each number by the one before it.
  2. Confirm Multiples: Divide 2525 by 55 to see if the pattern is consistent: 25÷5=525 \div 5 = 5. This indicates that each number might be 55 times the previous number.
  3. Find Missing Number: Now, divide 625625 by the number before it in the sequence (which we are trying to find) to see if the pattern holds: 625÷_____=5625 \div \_\_\_\_\_ = 5. To find the missing number, we need to perform the inverse operation, which is multiplication: _____×5=625\_\_\_\_\_ \times 5 = 625.
  4. Perform Division: To find the missing number, we divide 625625 by 55: 625÷5=125625 \div 5 = 125. This should be the missing number in the sequence if the pattern is consistent.
  5. Check Solution: To check if 125125 fits the pattern, we multiply it by 55 to see if we get the next number in the sequence, which is 3,1253,125: 125×5=625125 \times 5 = 625. This is incorrect, as we expected to get 3,1253,125, not 625625. We have made a math error.
