Recall that an odd number is a number that is one more than or less than twice an integer. Consider the sequence formed by the odd numbers. {1,3,5,7...} Write a formula for O(n), the nth odd number starting with n=1

Please help me.

Identify a1 and r for the geometric sequence an= -256(-1/4) n-1

Given the points a(-2, 1) and b(8, 6), find the coordinates of the point c on directed line segment ab, that partitions ab in the ration 2: 3.

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
