The second picture is got byremoving such a middle triangle from each of the red triangles of thefirst picture. The third picture shows the same thing done on the second0 How many red triangles are there in each picture?Taking the area of the original unout triangle as 1, compute thearea of a small triangle in each picture,* What is the total area of all the red triangles in each picture?Write the algebraic expressions for these three sequencesobtained by continuing this process, |
