Answer:
sequence 12,19,26,33
1st term = 12
comman difference = 19 - (12) = 7
comman term = a + (n-1)d
a= first term
d= difference
comman term = a + (n-1)d
= 12 + (n-1)(7)
= 12 +7n-7
= 7n +5
1st term --> n =1 = 7.1 + 5 = 12
2nd term --> n =2 = 7.2 + 5 = 14 + 5 = 19
64st term --> n =64 = 7.64+ 5 = 448+5 = 453

Answer:
Sue's scores for the four games in ascending order are: 97, 98, 98, 107
Step-by-step explanation:
Her modal score was 98. The mode is found by using the number that appears most often. This means that 98 has to appear at least two times out of the four scores.
Her range was 10. The range is found by taking the highest score and subtracting it from the lowest score. The highest score had to be greater than 98 and the lowest score had to be less than 98 since we know the mode was 98.
Her mean score was 100. This mean is found by adding all the numbers together and then dividing by the total numbers listed. Adding the four scores together and dividing by 4 will equal 100.
Used guess and test:
Highest Number, 98, 98, Lowest Number
107 - 97 = 10 (meets range requirement)
97 + 98 + 98 + 107 = 400
400/4 = 100 (meets the mean requirement)
I’m not too sure if I did it correct, but the answer I got was -6x^2+36. I just assumed you’d solve it as usual and then multiply (-3) after distributing-2 to x^2-6. Hope this helps.
