Answer:
1. Geometric Sequence Equation for Table A:

2. Arithmetic Sequence Equation for Table B:

3.
- 20th term for Geometric Sequence:

- 20th term for Geometric Sequence:

Explanation:
1. Geometric Sequence Equation for Table A:
The geometric sequence equation is given by the formula:
![\tt \[a_n = a_1 * r^((n-1))\]](https://img.qammunity.org/2024/formulas/mathematics/college/xppph07m1qj196fnxgb4zp5w5tfzlqhoi4.png)
where:
represents the nth term of the sequence.
is the first term of the sequence.
is the common ratio.
For Table A, since we don't have the actual values, we can represent the equation as:


2. Arithmetic Sequence Equation for Table B:
The arithmetic sequence equation is given by the formula:

where:
represents the nth term of the sequence.
is the first term of the sequence.
is the common difference.
For Table B, since we don't have the actual values, we can represent the equation as:


3. Finding Term 20 for both sequences:
In order to find the 20th term for both sequences, we need the actual values for
and d.
in the case of Table A


in the case of Table B.
