To find the missing output values, you can use the given input-output pattern to determine the relationship between the input and output values. Let's analyze the given pairs:

Input: 1 Output: 21
Input: 2 Output: 40
Input: 3 Output: 59

To determine the relationship between the input and output, we need to look for a pattern. Let's observe the changes in the output values:

From input 1 to input 2, the output increases by 19 (40 - 21 = 19).
From input 2 to input 3, the output increases by 19 again (59 - 40 = 19).

So, it seems that there is a constant difference of 19 between consecutive output values.

To find the missing output values for input 4, 5, 6, and 7, we can apply the same pattern:

For input 4:
Output = Previous Output + Difference
Output = 59 + 19 = 78

For input 5:
Output = Previous Output + Difference
Output = 78 + 19 = 97

For input 6:
Output = Previous Output + Difference
Output = 97 + 19 = 116

For input 7:
Output = Previous Output + Difference
Output = 116 + 19 = 135

So, the missing output values for inputs 4, 5, 6, and 7 are 78, 97, 116, and 135 respectively.
