Math Problem Statement

Какое число пропущено?

Solution

To solve the problem in the image, we need to figure out the missing numbers represented by the question marks (?) in the table. Here's an analysis based on the patterns and relationships:

Observations:

  1. The left side column values are multiplied by 2 to generate the right-side column values (39 × 2 = 74, 19 × 2 = 148, and so on).
  2. Each row appears to build towards a total of 2886, which is the sum of all elements in the bottom row.

Analysis:

  1. For the row totals:

    • The left column numbers are summed: 39+19+9+4+2+1=7439 + 19 + 9 + 4 + 2 + 1 = 74.
    • On the right column, the corresponding sums will also add up to the total 2886.
  2. For the missing multiplier ("?"), find what number satisfies the pattern of relationships when summed to equal the total.

Would you like me to explicitly calculate each missing value
