1/3, 0,1,-2.....neither geometric or arithmetic

Answer:

A. neither; 7, -20, 61

Step-by-step explanation:

\frac{1}{3} , 0 , 1, -2.....

If it is arithmetic then the difference between two terms should be a constant

Lets find the difference between two terms

0 - 0 - \frac{1}{3} = -\frac{1}{3}

1 - 0 = 1

-2 -1 = -3

 the difference is not a constant so it is not arithmetic.

If it is Geometric then the ratio between two terms should be same

\frac{0}{\frac{1}{3}} =0

1 divide by 0 is undefined

-2 divide by 1 = -2

the ratio is also not same. So it is not Geometric

The sequence is neither arithmetic nor geometric

neither; 7, -20, 61

Solve -5/3x + 7/3 = -5
Pavlova-9 [17]

Answer:

x = 24/15 = 8/3 = 2 2/3

Step-by-step explanation:

remember what you do to the left you must do to the right.

I converted the -5 to -15/3 so I could easily add or subtract

-5/3 x = -8/3

multiply both sides by -3/5 to cancel the coefficient of the x

x = -8/3 * -3/5 = 24/15
