A person is knitting a baby blanket that will consist of four triangles arranged to form a square. The first row of a triangle is created by placing two stitches. The second row of the triangle consists of four stitches. From that point on, each successive row contains one more stitch than the preceding row. How many stitches make up the 234th row? How many stitches are there in all 234 rows?
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
