<=> x=(c+d)/(b-a)
45 45 90 right triangle BCA
ratio of leg : leg : hypo = y : y: y√2
in this case hypo = 3√2 so leg = y = 3

Answer:
Step-by-step explanation:
1,4 ,13 , __________, 121
First term = 1
Second term = 1 + 3 = 4
Third term = 4 + 3*3 = 4 + 9 = 13
Fourth term = 13 + 3*3*3 = 13 + 27 = 40
2) 5, 12 , 33 ,_____
First term = 5
Second term = 5 + 7 = 12
Third term = 12 + 7*3 = 12 + 21 = 33
Fourth term = 33 + 7*3*3 = 33 + 63 = 99
