30. Establish the pattern in the arrangement of numbers in the sequence

$$
2,3,0,-2,-7,-14, \ldots
$$

and add two more numbers.
30. Each number, starting from the third, is equal to the sum of the two preceding ones minus five. Thus $2+3-5=0, 0-2-5=-7$ and so on. Therefore, after the number -14 will follow the number $-7-14-5=-26$, and after it $-14-26-5=-45$.
