To solve these problems, we need to skip count by 2s. This means we start with the first number and keep adding 2 to get the next number.
Let's look at the pattern for each row:
*
Row 1: Starts at 123. $123 + 2 = 125$, $125 + 2 = 127$. The next numbers are found by continuing to add 2.
*
Row 2: Starts at 171. $171 + 2 = 173$, $173 + 2 = 175$. Continue adding 2.
*
Row 3: Starts at 301. $301 + 2 = 303$, $303 + 2 = 305$. Continue adding 2.
*
Row 4: Starts at 751. $751 + 2 = 753$, $753 + 2 = 755$. Continue adding 2.
*
Row 5: Starts at 653. $653 + 2 = 655$, $655 + 2 = 657$. Continue adding 2.
*
Row 6: Starts at 983. $983 + 2 = 985$, $985 + 2 = 987$. Continue adding 2.
*
Row 7: Starts at 805. $805 + 2 = 807$, $807 + 2 = 809$. Continue adding 2.
*
Row 8: Starts at 425. $425 + 2 = 427$, $427 + 2 = 429$. Continue adding 2.
Here are the calculations for the missing boxes in each row:
