This pattern can be
represented by the explicit
expression of 2n.

  False

Step-by-step explanation:

The given sequence for n = 0, 1, 2, 3 is 0, 1, 4, 9. The suggested expression for the pattern is 2n. If we use the given values of n in that expression, we get a sequence of 0, 2, 4, 6. That is not the same sequence.

The explicit expression does not represent the given pattern. (False)

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2
