A3. The numbers $-7, -10$, and -13 follow a certain rule. Jure found the number that would follow -13 according to this rule. If he added the squares of the first and the obtained number, he would get:
(A) 23
(B) 81
(C) 207
(D) 245
(E) 305
A3. Each subsequent term in the sequence is 3 less, the number -13 is followed by the number -16. The sum of the squares of the first and the obtained number is $(-7)^{2}+(-16)^{2}=49+256=305$.
