Type the missing number in this sequence:
61, 53, 45, 37, 29,
, 13
21
To find the missing number in this sequence, it appears that each number decreases by 8.
Starting with 61, subtracting 8 gives us 53.
Continuing with 53, subtracting 8 gives us 45.
Continuing with 45, subtracting 8 gives us 37.
Continuing with 37, subtracting 8 gives us 29.
Continuing with 29, subtracting 8 gives us 21.
Continuing with 21, subtracting 8 gives us 13.
Therefore, the missing number in the sequence is 21.
To determine the missing number in the sequence, we can analyze the pattern or the rule that governs the progression of the numbers.
In this sequence, each number is decreasing by 8.
Starting from 61, we subtract 8 to get the next number: 61 - 8 = 53.
Continuing this pattern, we subtract 8 from each subsequent number to find the next one.
So, to find the missing number, we subtract 8 from the previous number, 13 - 8 = 5.
Therefore, the missing number in the sequence is 5.
