Question

Помогите алгебра пожалуйста

Answer 1

$a_{1}=2\\\\a_{2}=4\\\\a_{n+2}=a_{n}-a_{n+1} \\\\a_{1+2}=a_{1} -a_{1+1}\\\\a_{3}=a_{1}-a_{2} =2-4=-2\\\\\\a_{2+2}=a_{2}-a_{2+1}\\\\a_{4}=a_{2} -a_{3}=4-(-2)=4+2=6\\\\\\a_{3+2}=a_{3}-a_{3+1}\\\\a_{5}=a_{3}-a_{4}=-2-6=-8\\\\\\a_{4+2}=a_{4}-a_{4+1}\\\\a_{6}=a_{4}-a_{5}=6-(-8)=6+8=14\\\\Otvet:\boxed{2;4;-2,6;-8;14}$
