1、 123, 124, 125。 These three numbers are the same as the tens and the hundredths, so they are continuous. Because they are all three digits, which meets the requirements.
2、234,235,236。 These three digits are the same as the ten digits, and the hundred digits add 1, so they are also continuous. Because they are all three digits, they also meet the requirements.
3、345,346,347。 The single digit and ten digit of these three numbers increase by 1, and the hundred digit increases by 1, so they are also continuous. Because they are all three digits, they also meet the requirements.
These numbers are continuous, because their single digits are the same as the ten digits or increase by 1, while the hundred digits also increase by 1 or remain unchanged. Because they are all three digits, their hundreds of digits are integers starting from 1, and each digit is increased by 1 compared with the previous digit. So we can find many such continuous three digits.
The skill of writing numbers regularly;
1. Observe the law of numbers: observe a given series and find out the law between numbers. For example, some series are arranged according to the laws of odd number, even number, prime number and composite number. By observing the sequence, we can find the law between numbers and write the correct answer.
2. Find the law of increase and decrease: Some series are arranged according to the law of increase and decrease. In this case, we can observe the difference between the first number and the second number, and so on, to find the law of the whole series.
3. Find a specific pattern: Some series are arranged according to a specific pattern. For example, some number sequences are arranged in a repetitive number pattern, and some number sequences are arranged in a pattern that every other number appears. The correct answer can be found by observing the specific patterns in the sequence.
4. Using mathematical knowledge: Mathematical knowledge can help us better understand the laws of sequence. For example, for some series involving multiplication or division, you can use mathematical knowledge to calculate the correct answer.
