I will give brainliest What are the next three terms in the sequences below?

1. 2, 5, 7, 12, ___, ___, ___

2. 9, 11, 20, 31, ___, ___, ___

3. 2, 5, 10, 50, ___, ___, ___

4. 1, 3, 3, 9, ___, ___, ___

2, 5, 7, 12, 19, 31, 50

every number equals the two before it 7=5+2

9, 11, 20, 31, 51, 82, 133

every number equals the two before it 20=9+11

2, 5, 10, 50, 500, 25000 ,12500000

each number equals the two numbers before it multiplied 10=5*2

1, 3, 3, 9, 27, 243, 6561

ach number equals the two numbers before it multiplied 3=1*3

Hope This Helps :D

1. 2, 5, 7, 12, 19, 32, 51

2. 9, 11, 20, 31, 51, 82, 133

3. 2, 5, 10, 50, 500, 25000, 12500000

4. 1, 3, 3, 9, 27, 243, 6561

Step-by-step explanation:

In the first one, we are adding

2 + 5 = 7

5 + 7 = 12

7 + 12 = 19

19 + 32 = 51

So we're taking the second number and the answer each time we add.

The second one, we add just like the first one

9 + 11 = 20

11 + 20 = 31

20 + 31 = 51

31 + 51 = 82

51 + 82 = 133

The third one however, uses multiplication

2 * 5 = 10

5 * 10 = 50

10 * 50 = 500

50 * 500 = 25000

25000 * 500 = 12500000

Now, try to figure out number four.

Hint: It uses multiplication
