最佳解答:

Find a positive number between 5 and 45 so that the three numbers from a geometric sequence Let the number be X X/5 = 45/X X2 = 225 X = 15 Find 2 numbers between 16 and 54 so that the FOUR numbers from a geometric sequence Let the sequence be 16, 16r, 16r2 and 16r3 16r3 = 54 r3 = 54/16 = 27/8 r = 3/2 So the sequence is 16, 24, 36, 54 The missing numbers are 24 and 36
