The aim of this descriptive qualitative study is to find out the types of students' schemes in solving the problem of sequence patterns. The subjects of this study were 9 students of VIIIB grade at SMP Negeri 1 Sumowono by using purposive sampling. Using purposive sampling techniques that are chosen with consideration and with specific objectives. The validity of the data in this study is guaranteed by carrying out the Triangulation Method. Method triangulation is done by observation, tests, and interviews which are supported by documentation in the form of recordings and photographs. The results of this study showed that there were 13 schemes appeared when solving the sequence pattern problem involving; scheme of dividing the term into 2 with the same number, scheme of multiplying the different multiplication plus one, scheme of adding , scheme of decreasing U1 to U2 then multiplied by 2 and plus 1, scheme of the difference patterns, scheme of multiplying 2 numbers and adding the numbers, scheme of multiplying , scheme of adding , scheme of multiplying 3, scheme of adding , scheme of adding , scheme of adding menambahkan and scheme of adding 1 and the different number.
Keywords: Scheme, sequence of numbers, the configuration pattern of objects.
