Прошу, помогите пожалуйста!! Номер 595

Answer 1

A)$a_{n} =3n-2$
$a_{1} =3-2=1 \\ a_{2} =3*2-2=4 \\ a_{3} =3*3-2=7 \\ a_{10} =3*10-2=28$
б)$b_{n} =16* ( \frac{1}{2}) ^{n}$
$b_{1} = \frac{16}{2} =8 \\ b_{2} = \frac{16}{4} =4 \\ b_{3} = \frac{16}{8} =2 \\ b_{10} = \frac{16}{1024} = \frac{1}{64}$
в)$c_{n} =( -2)^{n}$
$c_{1} =-2 \\ c_{2} =4 \\ c_{3} =-8 \\ c_{10} =1024$
