12 + 15 = 27,
27 + 22 = 48,
48 + 27 = 75,
75 + 33 = 108,
108 + 39 = 147.
12 + 15 = 27,
27 + 22 = 48,

12-3 = 9.
7-12 = 15.
48-27 = 21.
75-48 = 27.
108-75 = 33.
And difference between each no is 6 i.e. 15-9 = 21-15 = 27-21 = 33-27 = 6.
So next no 39+108 = 147.
7-12 = 15.
48-27 = 21.
75-48 = 27.
108-75 = 33.
And difference between each no is 6 i.e. 15-9 = 21-15 = 27-21 = 33-27 = 6.
So next no 39+108 = 147.
