The sequence is alternatingly decreasing and increasing.
3 - 9 = -6
-6 + 18 = 12
12 - 8 = 4
4 + 16 = 20
Therefore, next term will be:
20 - 7 = 13
Answer:
46 and 59
Step-by-step explanation:
let the smaller number be n then the larger number is n + 13 and summing them gives the equation
n + n + 13 = 105
2n + 13 = 105 ( subtract 13 from both sides of the equation )
2n = 92 ( divide both sides by 2 )
n = 46
the 2 numbers are n = 46 and n + 13 = 46 + 13 = 59
<span> The </span>Slope<span> (also called Gradient) of a straight line shows how steep a straight line is. To calculate the slope, you need two points from the graph. Then, get the difference of the y and x values of the points and divide y by x. We do as follows:
slope = y2-y1 / x2 - x1 = 1.4 - 7.2 / 18.1 + 5 = -0.2511</span>
