### When a = 30,    and d = 100 The rule for the Arithmetic Sequence is

Explanation
The given rule for the arithmetic sequence is -70 + 100n. This means that each term in the sequence is found by subtracting 70 from 100 times the position of the term (n). So, when a = 30 and d = 100, we can plug these values into the rule to find the answer. Plugging in a = 30, we get -70 + 100n = 30. Solving for n, we find that n = 1. Therefore, the answer is -70 + 100(1) = 30.

### When a =  1,    and d = 4 The rule for the Arithmetic Sequence is

Explanation
The given rule for the Arithmetic Sequence is -3+4n. This means that each term in the sequence is obtained by adding 4 times the position of the term (n) to -3. For example, when n is 1, the term is -3+4(1) = 1. When n is 2, the term is -3+4(2) = 5. This pattern continues for all values of n, resulting in an arithmetic sequence.
