A pattern of dots is shown below. Determine the formula for the number of dots in term N and draw the patterns for the next three terms.

The given pattern shows:

• Term 0: 0 dots
• Term 1: 2 dots (arranged as one pair)
• Term 2: 4 dots (arranged as two pairs)
• Term 3: 6 dots (arranged as three pairs) The number of dots in each term is twice the term number. This can be represented by the formula $2N$, where $N$ is the term number.

The next three terms are Term 4, Term 5, and Term 6.

• For Term 4: $2 \times 4 = 8$ dots.
• For Term 5: $2 \times 5 = 10$ dots.
• For Term 6: $2 \times 6 = 12$ dots.
