Q. Type the missing number in this sequence:4, 16, 64, _, 1,024, 4,096
Identify Sequence Type: Is the given sequence geometric or arithmetic? Each term seems to be multiplied by a common ratio to obtain the next number. The given sequence appears to be geometric.
Find Common Ratio: Find the common ratio in the geometric sequence. Two consecutive terms are 4 and 16. 416=4 Common Ratio: 4
Multiply by Common Ratio: We multiply each term by the common ratio to get the next term. Sequence: 4,16,64,_,1,024,4,096Common Ratio: 4Find the missing number in the sequence. The number before the missing term is 64. 64×4=256Missing Number: 256
Find Missing Number: Verify the found number by checking if the next term after the missing number, when divided by the missing number, equals the common ratio. 1,024/256=4The common ratio is consistent.
