Q. Type the missing number in this sequence:4,16,64,256, _____, 4,096
Identify Type: Identify if the sequence is arithmetic or geometric. Each term seems to be multiplied by a common ratio to obtain the next number, indicating that the sequence is geometric.
Find Ratio: Find the common ratio in the geometric sequence.Two consecutive terms are 4 and 16.416=4Common Ratio: 4
Verify Ratio: Verify the common ratio with another pair of consecutive terms.Another pair of consecutive terms is 16 and 64.64/16=4This confirms that the common ratio is indeed 4.
Use Ratio: Use the common ratio to find the missing number in the sequence.The number before the missing term is 256.256×4=1024The missing number should be 1024.
Verify Number: Verify the found number by checking if the next term after the missing number follows the common ratio.The number after the missing term is 4096.4096/1024=4This confirms that 1024 is the correct missing number in the sequence.
