Type the missing number in this sequence: 60, 50, _____, 30, 20

Observe and Calculate: We observe that the sequence is decreasing. To find the pattern, we subtract the second number from the first number. Calculation: 60 - 50 = 10 Reasoning: The sequence appears to be decreasing by 10 each time. Math error check: 60 - 50 = 10, which is correct. Apply Pattern to Find Missing Number: We apply the pattern to find the missing number by subtracting 10 from the second number in the sequence. Calculation: 50 - 10 = 40 Reasoning: If the sequence decreases by 10 each step, then the number before 30 should be 40. Math error check: 50 - 10 = 40, which is correct.

Q. Type the missing number in this sequence:

\newline

60,\; 50,\; \_{\_\_\_\_},\; 30,\; 20

Observe and Calculate: We observe that the sequence is decreasing. To find the pattern, we subtract the second number from the first number. $\newline$ Calculation: $60 - 50 = 10$ $\newline$ Reasoning: The sequence appears to be decreasing by $10$ each time. $\newline$ Math error check: $60 - 50 = 10$ , which is correct.
Apply Pattern to Find Missing Number: We apply the pattern to find the missing number by subtracting $10$ from the second number in the sequence. $\newline$ Calculation: $50 - 10 = 40$ $\newline$ Reasoning: If the sequence decreases by $10$ each step, then the number before $30$ should be $40$ . $\newline$ Math error check: $50 - 10 = 40$ , which is correct.
