1. The problem is to identify which number among 98, 70, 35, 20, and 10 fits a certain pattern or condition. 2. Since no specific condition is given, let's analyze the numbers for common mathematical properties such as divisibility, factors, or sequences. 3. Check if any number is a multiple or factor of another: - 98 = 2 \times 7^2 - 70 = 2 \times 5 \times 7 - 35 = 5 \times 7 - 20 = 2^2 \times 5 - 10 = 2 \times 5 4. Notice that 35, 20, and 10 are factors or multiples related to 70 and 98. 5. If the question is which number is a factor of all others or fits a pattern, 10 is a factor of 70 and 20 but not 35 or 98. 6. Without additional context, the best guess is that 70 is the number that connects most others as it shares factors with 98, 35, 20, and 10. Final answer: 70
