3 5 15 75 1125
Assuming the following reasoning is correct:
3x5=15
5x15=75
15x75=1125
The sequence appears to be multiplying by increasing factors: (3 \times 5 = 15) and (15 \times 5 = 75). Following this pattern, the next number would be (75 \times 5 = 375). Therefore, the next number in the sequence is 375.
The next number in the sequence 3-15-6-30-21 is -207.
The answer is 75. Starting at 10 the sequence is times 3, divided by 2, plus 1, times 3, divided by 2, plus 1. So the next number is times 3 = 75.

Times 3, cut in half, plus 1. The next number is 75.
The sequence appears to be multiplying by increasing factors: (3 \times 5 = 15) and (15 \times 5 = 75). Following this pattern, the next number would be (75 \times 5 = 375). Therefore, the next number in the sequence is 375.
The next answer in the sequence is 75 The sequence is times 3, divided by 2, plus 1 Example 10*3=30 30/2=15 15+1=16 16*3=48 48/2=24 24+1=25 25*3=75
The next number in the sequence 3-15-6-30-21 is -207.
The answer is 75. Starting at 10 the sequence is times 3, divided by 2, plus 1, times 3, divided by 2, plus 1. So the next number is times 3 = 75.

15 since you multiply by 3 then subtract 3 in sequence
28
The sequence subtracts consecutive odd numbers. In this sequence it goes -1, -3, -5, -7. The next number will be 75 (84 - 9).
Times 3, cut in half, plus 1. The next number is 75.
This sequence appears to follow the relation *3, /2 , +1, *3, /2, +1,........ By applying the above relation to the existing numbers we see that 24 + 1 = 25. Hence we apply the *3 logic to 25. We obtain 25 * 3 = 75 as the next number in the sequence.
The next number in the sequence is 48.
