Final answer:
The next number in the sequence after 5, 15, 25, 35 is 45, as the sequence increases by 10 with each subsequent number.
Step-by-step explanation:
The next number in the sequence 5, 15, 25, and 35 is determined by finding the pattern within the sequence. We notice that each number is increasing by 10. Therefore, to find the next number, we add 10 to the last number in the sequence, which is 35.
Calculation:
35 + 10 = 45
So, the next number in the sequence is 45.
