Question

19 18 22 21 25 what number comes next

Answer 1

The question involves finding the next number in a sequence by identifying the pattern of alternating between decreasing by 1 and increasing by 4. The next number after 25, following the pattern, is 24.

Step-by-step explanation:

The student's question '19 18 22 21 25 what number comes next' involves recognizing a pattern and predicting the next number in the sequence. To solve this, first we need to identify the pattern present in the numbers given. Observing the sequence, we can see an alternating pattern of decreasing by 1 and then increasing by 4:

• 19 (decrease by 1) = 18
• 18 (increase by 4) = 22
• 22 (decrease by 1) = 21
• 21 (increase by 4) = 25

Following this pattern, the next step would be to decrease the last number by 1. Therefore, the next number after 25 would be:

25 (decrease by 1) = 24.

The answer to the question '19 18 22 21 25 what number comes next' is 24.

Answer 2

Answer: 29

Step-by-step explanation:

To identify the pattern in the given sequence and find the next number, let's examine the differences between each consecutive pair of numbers:

1st and 2nd numbers: 18 - 19 = -1

2nd and 3rd numbers: 22 - 18 = 4

3rd and 4th numbers: 21 - 22 = -1

4th and 5th numbers: 25 - 21 = 4

The pattern alternates between subtracting 1 and adding 4. Therefore, to find the next number in the sequence:

5th number + 4 = 25 + 4 = 29

So, the next number in the sequence is 29.
