None of these

To find the missing number in the sequence, observe the differences between consecutive terms:

- The first difference: 32 - 27 = 5

- The second difference: 42 - 32 = 10

- The third difference: 57 - 42 = 15

- The fourth difference: 77 - 57 = 20

Notice the differences increase by 5 each time (5, 10, 15, 20). The next difference should be 25.

- Calculate the next term:

- 77 + 25 = 102

- Choose the correct option:

- Option 1: 102

- Option 2: 92

- Option 3: 112

- Option 4: 99

- Option 5: None of these
