Is the sequence arithmetic, geometric, or neither

The first one is arithmetic, the second one is geometric, the third one is neither, the fourth one is geometric, the last one is arithmetic.

The first question goes up by a rate of -100 each time, so its arithmetic.

The second one goes up by a rate of *5 each time, so its geometric.

The third one is inconsistent so it is neither.

The fourth one goes by a factor of *-6 each time, so its geometric.

The last one goes up by a rate of -10 each time, so its arithmetic.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
