Answer:

Step-by-step explanation:

The slope is the change of y over the change of x.

Therefore, the slope is -3.
The common difference, d, can be determined by subtracting the two consecutive values:
1 - 5 = -4
-3 - 1 = -4
-7 - -3 = -4
Then, using the equation:
an = a1+ d(n-1)
a_21 = 5 + (-4)(21 - 1)
a_21 = -75
The answer is letter D. I hope I was able to help you. Have a good day!
for the first one $5.34 ÷ 6 so if u type that into a calculate it will say $0.89
0.46<span> = 7/15 </span>
0.46<span> = 46/99</span>
