- 27 + 10 = 37
- 10 + 34 = 44
- 34 + 37 = 71
- 37 + 7 = 44
- 37 + 44 = 81
- 44 + 71 = 115
- 71 + 44 = 115
- 81 + 115 = 196
- 115 + 115 = 230
- 196 + 230 = 426
- 290 + ? = ? (bottom row missing one block, but only one block shown with 290, so likely a single block above it is missing; however, based on pyramid structure, the bottom row should have two blocks summing to the one above. Since only one is given, we assume the other is missing and the top of that small pyramid is missing. But the main pyramid is complete up to 426. The separate bottom part with 290 likely is unrelated or incomplete. We focus on the main pyramid.)
Final filled pyramid values from bottom up:
Row 1 (bottom): 27, 10, 34, 37, 7
Row 2: 37, 44, 71, 44
Row 3: 81, 115, 115
Row 4: 196, 230
Row 5: 426
The separate block with 290 and one missing block below it cannot be solved without more information. Assuming it's a separate exercise, if the top is missing and bottom has 290 and one unknown, we can't determine. But since the instruction is to fill missing blocks in the pyramid, and the pyramid is complete except for the separate 290 which seems out of place, we ignore it or note it's incomplete.
But re-examining: the image shows a pyramid with 5 rows, and then separately at the bottom, a single block with 290 and one block below it missing. This might be a separate small pyramid. If so, and if the block above is the sum, then:
Let the missing block be x.
Then x + 290 = ? but the block above is not given. So it's unsolvable as presented.
Given the context, likely the 290 is meant to be part of the pyramid, but it doesn't fit. Perhaps it's a typo or misplacement.
Since the main pyramid is solvable and complete, we provide the missing values for it.
Missing blocks in the main pyramid:
- Row 2: 37, 44, 71, 44 (all calculated)
- Row 3: 81, 115, 115
- Row 4: 196, 230
- Row 5: 426
The separate 290 with one missing block below: if we assume the block above is missing and the two below are 290 and x, then without the top value, we can't find x. So we omit it.
Thus, the solution is the completed main pyramid as above.
