Answer with Step-by-step explanation:
We are given a pattern
2 7 8 3 12 9
and we are asked to find the next term of this pattern
2+1=3
7+5=12
and 8+1=9
We can view this pattern in the set of three numbers and then, the next three are formed by adding one, five & one, respectively.
See these COLUMNS of groups of three:
2 3 4
7 12 17
8 9 10
Hence, next number in the pattern is:
4
