To solve for the unknown values in the pyramid structure, we'll use the typical method where each brick is the sum of the two bricks directly below it. Let's work from the bottom up.

Given Information:

• Top row (1 brick): 2435
• Second row (2 bricks): Unknown
• Third row (3 bricks): Middle brick is 688
• Bottom row (4 bricks): Leftmost brick is 210

Pyramid Structure:

       2435
      ?    ?
    ?   688   ?
 210  ?    ?   ?

Step 1: Fill in the Bottom Row (4 bricks)

Let's denote the bricks in the bottom row as follows:

• Brick A (leftmost): 210
• Brick B: Unknown
• Brick C: Unknown
• Brick D: Unknown

Step 2: Determine the bricks in the Third Row

The middle brick of the third row is given as 688. The bricks in the third row can be expressed as:

• Brick E (left): A + B = ?
• Brick F (middle): B + C = 688
• Brick G (right): C + D = ?

Step 3: Calculate the unknowns

Since we only know one brick in the third row, we can't directly solve for the unknowns without more information. However, let's denote the unknowns in the bottom row as B, C, and D:

• $E = A + B = 210 + B$
• $F = B + C = 688$
• $G = C + D = ?$

From the equation $F = B + C = 688$, we can solve for one variable in terms of the other:

$C = 688 - B$

However, without additional values for B and D, we can't determine the exact values for the other unknowns.

Step 4: Determine the Second Row

The bricks in the second row can be expressed as:

• Brick H (left): E + F = (210 + B) + (688)
• Brick I (right): F + G = 688 + (C + D)

Step 5: Top Brick Calculation

Finally, the top brick is the sum of the two bricks in the second row:

$2435 = H + I$

This is a complicated problem without enough information to determine a unique solution for all unknowns. Additional data or conditions are needed to solve for B, C, D, E, G, H, and I.

Tip:

Always start with known values at the base of the pyramid and work upwards to find unknowns. If stuck, check if any assumptions or approximations can be made to simplify the problem.
