1. The problem is to find the missing number in the sequence: 904, 914, _, 926, 928, 938, 940. 2. To solve this, observe the pattern in the differences between consecutive numbers. 3. Calculate the differences: - 914 - 904 = 10 - _ - 914 = ? - 926 - _ = ? - 928 - 926 = 2 - 938 - 928 = 10 - 940 - 938 = 2 4. Notice the pattern in differences alternates between 10 and 2. 5. Since 914 - 904 = 10, the next difference should be 2, so the missing number is 914 + 2 = 916. 6. Verify the next difference: 926 - 916 = 10, which fits the pattern. 7. Therefore, the complete sequence is 904, 914, 916, 926, 928, 938, 940.
