Answer :
In this question, we are examining patterns in sequences of numbers. Let's break down each pattern described:
Adding 2: 20, 22, 24, 26
- In this sequence, each number is obtained by adding 2 to the previous number.
- For instance, starting at 20, adding 2 gives us 22. Adding 2 to 22 results in 24, and adding 2 to 24 results in 26.
Subtracting 4: 39, 35, 31, 27
- In this sequence, each number is derived by subtracting 4 from the previous number.
- Starting with 39, if we subtract 4, we get 35. Subtracting 4 from 35 results in 31, and subtracting 4 from 31 gives us 27.
Adding 5: 25, 30
- Here, the sequence increases by adding 5.
- Starting at 25, adding 5 results in 30.
In the given example, another sequence is demonstrated for better understanding:
Adding 6:
- Starting at 44, adding 6 gives 50. Adding another 6 to 50 results in 56.
Subtracting 9:
- Starting at 62, subtracting 9 gives 53. Subtracting another 9 from 53 results in 44.
Understanding these patterns helps in determining how sequences progress and predicting the next numbers in each pattern.
