Which number completes the sequence: 42, 37, 47, 42, ?

To determine which number completes the sequence: 42, 37, 47, 42, it is helpful to observe the pattern in the numbers presented.

Starting with the first number, 42, if we take a closer look at the sequence, we can see the following:

• The first number is 42.
• The second number is 37, which is 5 less than 42.
• The third number, 47, is 10 more than 37.
• The fourth number returns to 42, which is 5 less than 47.

The sequence alternates between decreasing by 5 and then increasing by 10. Following this pattern, after 42, we would expect to add 5. Hence, calculating 42 + 5 gives us 47.

This reasoning confirms that 47 logically follows the pattern of the sequence.
