Guided solution
To find the next number in the pattern, we need to identify the rule that the sequence follows. By examining the differences between consecutive numbers, we can see that each number increases by 28.
The problem requires recognizing a pattern in a sequence of numbers, which involves understanding arithmetic sequences and differences. This can be moderately challenging for grade-4 students.
The pattern increases by 28 each time (14 + 28 = 42, 42 + 28 = 70, etc.), so the next number after 126 is 126 + 28 = 154.
