Number Patterns: Sequences Involving Addition - Finding the First Term
Problem Statement:
Given the sequence: __, -2, 5, 12, 19, determine the missing number then drive the robot to the missing term. You can input negative numbers into the blocks to move the robot backwards.
```/* Code generated by RoboBlockly v2.0 */
#include <linkbot.h>
CLinkbotI robot;
double radius = 1.75;

robot.driveDistance(-9, radius);
