Answer
$\left\{9, 10, 11, 12, 13,14\right\}$
Work Step by Step
Natural numbers are the numbers $1, 2, 3, . . . , 8, 9, 10, . . ., 14, 15, 16, . . .$.
Thus, the natural numbers greater than 8 and less than 15 are 9, 10, 11, 12, 13, and 14.
Therefore, writing the given set in roster method gives:
$\left\{9, 10, 11, 12, 13,14\right\}$
