Q. Type the missing number in this sequence:1, _____, 25, 125, 625
Identify Pattern: Identify the pattern in the sequence: 1, _, 25, 125, 625. We notice that each number seems to be a power of a certain base number.
Determine Base Number: Determine the base number and the pattern of exponents.The numbers 1, 25, 125, and 625 are all powers of 5: 50, 52, 53, and 54 respectively.
Find Missing Term: Find the missing term in the sequence.Since the sequence is increasing and we have 50 and 52, the missing term should be 51.Calculate 51 to find the missing number.51=5
Verify Pattern: Verify the pattern with the calculated missing number.The sequence now reads: 1(50), 5(51), 25(52), 125(53), 625(54).This confirms the pattern of consecutive powers of 5.
