Final answer:
To predict the next number in a sequence, you add a constant value to each term in the sequence.
Step-by-step explanation:
To predict the next number in a sequence, you can use the method of adding a constant value. This means that you add the same number to each term in the sequence to get the next term. For example, if the sequence is 2, 4, 6, 8, the constant value is 2 because you add 2 to each term to get the next term: 8 + 2 = 10.
Option b) By adding a constant value is the correct answer to predict the next number in a sequence.
