The slope is 3/10, and just graph 2 points ( so like .3,1 and .9,2) and just use Desmos to figure out the line using the y=3/10x+3.64 and just type it in
The 8th term would be 8.25 because it decreases by .25 each term. 10,9.75, 9.5, 9.25, 9, 8.75, 8.5, 8.25
The answer is 12. My explanations is that LCM is the smallest number that both numbers can fit into. 12 fits into 12 once, and 4 fits into 12 3 times, so 12 is the answer.
The answer is: (2x + 1) (x + 3) .
