Adds 4 each time and 5-4=1 so nth term is 4n + 1
The width of the confidence interval is twice the margin of error. The lower bound of the confidence interval is the observed score minus the margin of error;
Using the quadratic formula
2 consecutive odd positive integers....x and x + 2
x^2 + (x + 2)^2 = 130
x^2 + (x + 2)(x + 2) = 130
x^2 + x^2 + 4x + 4 = 130
2x^2 + 4x + 4 = 130
2x^2 + 4x + 4 - 130 = 0
2x^2 + 4x - 126 = 0
2(x^2 + 2x - 63) = 0
2(x - 7)(x + 9) = 0
x - 7 = 0
x = 7
x + 9 = 0
x = -9 (cant be this one because it is negative
so x = 7...and x + 2 = 7 + 2 = 9......ur 2 numbers are 7 and 9
