GOOD LUCK

1.) 40 3.) common difference is represented by the letter d, d= -5 5.) 11 or 11th term 6.) d=-8 7.) 5, 8, 11, 14, 17 8.) 75 9.) 0

i don't have an answer for 2, 4, 10 sorry

Step-by-step explanation:

1.) d=a2-a1,12-5=7

the d=7

5+7=12+7=19+7=26+7=33+7=40

3.) d=a2-a1, 3-8= -5

d= -5

5.) d=5, a1=6 add 5 until you get 56

6+5=11+5=16+5=21+5=26+5=31+5=36+5=41+5=46+5=51+5=56
