Find the tenth term in each sequence. -1,2/3,7/3,4,17/3
Luba_88 [7]

It'a an arithmetic sequence:

a_1=-1\\\\a_2=-1+\dfrac{5}{3}=-\dfrac{3}{3}+\dfrac{5}{3}=\dfrac{2}{3}\\\\a_3=\dfrac{2}{3}+\dfrac{5}{3}=\dfrac{7}{3}\\\\a_4=\dfrac{7}{3}+\dfrac{5}{3}=\dfrac{12}{3}=4\\\\a_5=4+\dfrac{5}{3}=\dfrac{12}{3}+\dfrac{5}{3}=\dfrac{17}{3}\\\vdots\\\\\text{The general formula for nth term of an arithmetic sequence}\\\\a_n=a_1+(n-1)d\\\\\text{We have}\ a_1=-1\ \text{and}\ d=\dfrac{5}{3}.\\\\\text{Substitute}\\\\a_n=-1+(n-1)\left(\dfrac{5}{3}\right)=-1+\dfrac{5}{3}n-\dfrac{5}{3}=\dfrac{5}{3}n-\dfrac{3}{3}-\dfrac{5}{3}

\boxed{a_n=\dfrac{5}{3}n-\dfrac{8}{3}}

Answer:

The gradient of the graph below is \mathbf{\frac{3}{2} }

Step-by-step explanation:

We need to calculate the gradient of the graph

The gradient of graph is actually slope of the graph.

The slope of graph can be calculated using formula: Slope=\frac{y_2-y_1}{x_2-x_1}

Taking any 2 points on graph i.e

(1,0) and (-1,-3)

We have x_1=1, y_1=0, x_2=-1,y_2=-3

Putting values and finding gradient:

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-3-0}{-1-1}\\Slope=\frac{-3}{-2}\\Slope=\frac{3}{2}

So, The gradient of the graph below is \mathbf{\frac{3}{2} }
