A:
Answer:Step-by-step explanation:The sum of a number and the next the result is is alternating 4 an -4(-4) +8 = 48+(-12) = -4(-12) + 16 = 417)20)Numerator is increased by 2 Numerator is increased by 1 9th is 18/11 (If 2/3 is considered the first)9th is 16/10 if  1/1 is considered first)   The sum The sum of each fraction is 3 more than the sum of the previous fraction2+3 = 54+4 = 8 (5+3)6+5=11 (8+3)8+6=14 (11+3)......23)The next number is 0.7 more than the previous number5.2/4.5=0.74.5/3.8=0.73.8/3.1=0.7
