The arithmetic sequence `(a_i)` is defined by the formula:

`a_i = A + D(i - 1)`

What is `a_{N}`, the ordinalThrough20(N) term in the sequence?

A + D * (N - 1)

From the given formula, we can see that the first term of the sequence is `A` and the common difference is `D`.

The second term is simply the first term plus the common difference.

Therefore, the second term is equal to `a_2 = A + D = A + D`.

To find `a_{N}`, we can simply substitute `i = N` into the given formula.

Therefore, the ordinalThrough20(N) term is equal to `a_{N} = A + D (N - 1) = A + D * (N - 1)`.

`a_1 = A`
`a_i = a_{i-1} + D`

From the given formula, we can see that the first term of the sequence is `A` and the common difference is `D`.

The second term is simply the first term plus the common difference.

Therefore, the second term is equal to `a_2 = a_1 + D = A + D = A + D`.

To find the ordinalThrough20(N) term, we can rewrite the given recurrence as an explicit formula.

The general form for an arithmetic sequence is `a_i = a_1 + d(i - 1)`. In this case, we have `a_i = A + D(i - 1)`.

To find `a_{N}`, we can simply substitute `i = N` into the our formula.

Therefore, the ordinalThrough20(N) term is equal to `a_{N} = A + D (N - 1) = A + D * (N - 1)`.
