The solution of sequence provided is 2.
The sequence provided is 5, 5, 2, 10, _, 27. The pattern in this sequence can be determined by looking at the relationship between each consecutive number.
In this case, we can see that starting from 5, the next number is also 5. Then, the number 2 follows and the number 10 follows after that. And the next number is 27.
The pattern in the sequence appears to be multiplying the previous number by 2 and then subtracting 3.
5 x 2 - 3 = 7
5 x 2 - 3 = 7
2 x 2 - 3 = 1
10 x 2 - 3 = 17
So when we apply this pattern to the next blank number, we get 17 x 2 - 3 = 27. which match the last number of the sequence.
This pattern can be represented mathematically as:
x(n) = 2x(n-1) -3
where x(n) is the nth number in the sequence, x(n-1) is the (n-1)th number in the sequence and -3 is a constant number.
