Ensure that the final number in your chain matches the logic of the entire scheme. If there are branching arrows, check that each path leads to a mathematically sound conclusion.

: Understanding how one change affects the next step in a sequence.

Look at the numbers written above the arrows. In this particular lesson, the operations are often simple increments or decrements (e.g., adding or subtracting 1).

), and the goal is to determine the starting or intermediate values based on the logic of the sequence. 1. Analyze the Visual Scheme
