the answer is multiply the current term by 2 and add 1 to find the next term.
Well, If the area of ABC is 20cm², Then the area of ABS would be 10cm² and the area of ACS would also be 10cm². You basically are just cutting the ABC in half. I hope this helps!
You would do 1u-1-4u-4 and so you have 3u-5
