Finding the Solution
Let’s examine the solution together. First, look at the difference between the first two numbers in the sequence: 99 – 92 = 7. Next, the difference between the second and third numbers: 92 – 86 = 6. Continuing this pattern, the difference between 86 and 81 is 5, and between 81 and 77 is 4. The pattern is 7, 6, 5, 4.
To find the final solution, subtract 3 from 77, which gives us 74.
SOLUTION: 77 – 3 = 74.
