Q. Type the missing number in this sequence:6, _, 216, 1,296, 7,776
Observe Pattern: Let's observe the pattern in the given sequence. We notice that each number seems to be a multiple of 6, and it looks like each subsequent number is a power of 6. To confirm this, let's check if 216, 1,296, and 7,776 are indeed powers of 6.
Check 216: First, we check if 216 is a power of 6. We can do this by repeatedly dividing 216 by 6 until we reach 1 or a non-integer number.216÷6=3636÷6=66÷6=1Since we reached 1 by dividing by 6 three times, 216 is 6 to the power of 62 (63).
Check 1,296: Next, we check if 1,296 is a power of 6. We use the same method as before.1,296÷6=216 (which we already know is 63)So, 1,296 is 64.
Check 7,776: Finally, we check if 7,776 is a power of 6. 7,776÷6=1,296 (which we already know is 64) So, 7,776 is 65.
Confirm Pattern: Now that we have confirmed the pattern, we can see that the sequence is increasing by one power of 6 each time. The sequence starts with 6, which is 61. The next term should be 62, followed by 63, 64, and 65.
Calculate Missing Number: Let's calculate 62 to find the missing number in the sequence.62=6×6=36So, the missing number in the sequence is 36.
