Is the sequence -6,-11,-16,-21,-26 is arithmetic true or false ?

True

Step-by-step explanation:

For the sequence to be arithmetic the difference d between consecutive terms must be equal.

- 11 - ( - 6) = - 11 + 6 = - 5

- 16 - (- 11) = - 16 + 11 = - 5

- 21 - (- 16) = - 21 + 16 = - 5

- 26 - (- 21) = - 26 + 21 = - 5

Since there is a common difference between terms the sequence is arithmetic.

Yes

Step-by-step explanation: The terms are decreasing every five units.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
