The sequence you've provided is: 1, 2, 3, 5, ...
This sequence does not follow a simple arithmetic or geometric pattern. However, we can observe how it is constructed:
- The first term is 1.
- The second term is 2.
- The third term is 3.
- The fourth term is 5.
If we look closely, we can see that each term, starting from the third term, is the sum of the previous two terms:
- 1 + 2 = 3
- 2 + 3 = 5
This suggests that the sequence might be a variation of the Fibonacci sequence, where each term is the sum of the two preceding terms. More specifically, this sequence can be described as:
- \(a_1 = 1\)
- \(a_2 = 2\)
- \(a_n = a_{n-1} + a_{n-2} \) for \(n \geq 3\)
Thus, the next term in this sequence would be:
- 3 + 5 = 8
So the sequence continues: 1, 2, 3, 5, 8, ...
In summary, this sequence is a modification of the Fibonacci sequence.
