Answer 1

$a_{n} = 3n - 6 \\a_{1} =? \\ a_{2} =? \\ a_{3} =? \\ a_{4} =? \\ a_{10} =?$

Решение:

$a_{1} = |n = 1| = 3 \times 1 - 6 = 3 - 6 = - 3 \\a_{2} = |n = 2| = 3 \times 2 - 6 = 0 \\ a_{3} = |n = 3| = 3 \times 3 - 6 =3 \\ a_{4} = |n = 4| = 3 \times 4 - 6 =6 \\ a_{10} = |n = 10| = 3 \times 10 - 6 =24$

Ответ:

$a_{1} = - 3 \\ a_{2} =0 \\ a_{3} =3 \\ a_{4} =6 \\ a_{10} =24$
