Q. Type the missing number in this sequence:5,25,125,_,3,125,15,625
Observe pattern in sequence: We observe the pattern in the sequence to determine the rule that generates it. Each number appears to be multiplied by 5 to get the next number.
Check pattern by multiplying: We check the pattern by multiplying the first number by 5: 5×5=25, which matches the second number in the sequence.
Apply rule to find missing number: We continue to check the pattern by multiplying the second number by 5: 25×5=125, which matches the third number in the sequence.
Calculate missing number: Now, we apply the same rule to find the missing number by multiplying the third number by 5: 125×5.
Verify pattern consistency: We calculate 125×5=625. This should be the missing number in the sequence.
Confirm pattern correctness: To ensure the pattern is correct, we check the next number by multiplying the missing number we found by 5: 625×5=3,125, which matches the next number in the sequence.
Confirm pattern correctness: To ensure the pattern is correct, we check the next number by multiplying the missing number we found by 5: 625×5=3,125, which matches the next number in the sequence.Finally, we verify the last given number by multiplying 3,125 by 5: 3,125×5=15,625, which confirms the pattern is consistent and correct.
