<em>The numbers in parentheses are carried from previous sum</em>
Start from the right
Write 0, carry 1
2 4 5 6 7 3 8 9
+ 3 5 4 3 2 6 1 1
----------------------------
0
Write 0 carry 1
2 4 5 6 7 3 8 9
+ 3 5 4 3 2 6 1 1
----------------------------
0 0
Write 0 carry 1
2 4 5 6 7 3 8 9
+ 3 5 4 3 2 6 1 1
----------------------------
0 0 0
Write 0 carry 1
2 4 5 6 7 3 8 9
+ 3 5 4 3 2 6 1 1
----------------------------
0 0 0 0
Write 0 carry 1
2 4 5 6 7 3 8 9
+ 3 5 4 3 2 6 1 1
----------------------------
0 0 0 0 0
Write 0 carry 1
2 4 5 6 7 3 8 9
+ 3 5 4 3 2 6 1 1
----------------------------
0 0 0 0 0 0
Write 0 carry 1

----------------------------
6 0 0 0 0 0 0 0
Hence:

The term to term rule is multiplying by 4 and if we continue doing this, we will move towards very large positive numbers.
This sequence, therefore, diverges to infinity
#1 is A & B (points connect)
#2 is A & B & D (because they all touch)
#3 is Plane DFG & Plane GFA
#4 is A & B & D & F
Answer is 181 sandwiches
Working steps
Firstly you want to work backwards and turn in equation
30*2+26*4+17=X
So 60+104+17=X
That means 181=X
