Answer:

198 if thirty rows after the first three, 186 if thirty includes original three

Step-by-step explanation:

Formula if including or not original three:

4(x)+78=total (78 from adding originals 30+26+22)

Formula if including originals:

4(27)+78 (x=number of rows, clearly)

108+78=

186

Formula if Not including originals :

4(30)+78

120+78=

198
