उत्तर
First number: 2
Second number: 3 (i.e. 2 + 1)
Third number: 6 (i.e. 3 + 3)
Fourth number: 11 (i.e. 6 + 5)
Fifth number: 18 (i.e. 11 + 7)
Addition of sequence of odd numbers i.e. 1, 3, 5, 7 …
Thus, next number will be
18 + 9 = 27
27 + 11 = 38
38 + 13 = 51
51 + 15 = 66
66 + 17 = 83
So, the final pattern will be: 2, 3, 6, 11, 18, 27, 38, 51, 66, 83.
