okay, so the pattern is multiplying by 4. so to find the next two numbers: 128 times 4=512 times 4=2048. so all six numbers are 2, 8, 32, 128, 512, and 2048. Add all six together and you get D-2730.
2, 8, 32, 128, 512, 2048, and here's why: The pattern is the number times 4. 1:2 2: 2*4 is 8, 3: 8*4 is 32, 4: 32*4 is 128, 5: 128*4 is 512, 6: 512*4 is 2,048.
