The pattern is
3, 6, 9
102 + 3 = 105
105 + 6 = 111
111 + 9 = 120
- - - - - - - - - - -
120 + 3 = 123
123 + 6 = 129
129 + 9 = 138
- - - - - - - - - - -
138 + 3 = 141
141 + 6 = 147
147 + 9 = 156
- - - - - - - - - - -
156 + 3 = 159
159 + 6 = 165
165 + 9 = 174
- - - - - - - - - - -
174 + 3 = 177
177 + 6 = 183
183 + 9 = 192
- - - - - - - - - - - -
192 + 3 = 195
195 + 6 = 201
201 + 9 = 210

Add 3-6-9-3-6; 9-12-15-9-12; 15-
so
102, 105, 111, 120, 123, 129, 138 , 150 , 165 , 174, 186, 201

All I can tell is that they are all multiples of 3.
102/3=34, 105/3=35, 111/3=37,
120/3=40, 123/3=41, 129/3=43,
_______, ________, _______,
174/3=58, 186/3=62, 201/3=67
so 3 of these numbers have to be the answer.
132, 135, 138, 141, 144, 147, 150, 153, 156,

the pattern is
3, 6, 9, 3, 6, 9 and then it goes to 9, 12, 15, 9, 12, 15 so you're missing numbers are
138, 150, 165
It wasn't that easy!

add 3 then 6 then 9 then continue with 3, 6, 9 just like that.

129+9=138
138+3=141
141+6=147
The last three numbers make no sense and do not fit the pattern of the first nine, so discard them and it makes sense then.
