Question

Encuentra los primeros seis elementos de la sucesiones cuyo termino generales son los siguientes
2xn=
5xn=
5xn-1=
2xn+5=

Answer 1

- Para hallar los primeros seis elementos de las sucesiones debemos reemplazar a $n$ por los números $1,2,3,4,5,6.$

$a_{n} = 2.n$
$a_{1} = 2 . 1 = 2$
$a_{2} = 2. 2 = 4$
$a_{3} = 2 . 3 = 6$
$a_{4} = 2 . 4 = 8$
$a_{5} = 2 . 5 = 10$
$a_{6} = 2 . 6 = 12$

$a_{n} = 5 . n$
$a_{1} = 5 . 1 = 5$
$a_{2} = 5 . 2 = 10$
$a_{3} = 5 . 3 = 15$
$a_{4} = 5 . 4 = 20$
$a_{5} = 5 . 5 = 25$
$a_{6} = 5 . 6 = 30$

$a_{n} = 5 . n - 1$
$a_{1} = 5 . 1 - 1 = 5 - 1 = 4$
$a_{2} = 5 . 2 - 1 = 10 - 1 = 9$
$a_{3} = 5 . 3 - 1 = 15 - 1 = 14$
$a_{4} = 5 . 4 - 1 = 20 - 1 = 19$
$a_{5} = 5 . 5 - 1 = 25 - 1 = 24$
$a_{6} = 5 .6 - 1 = 30 - 1 = 29$

$a_{n} = 2.n+5$
$a_{1} = 2 . 1 + 5 = 2 + 5 = 7$
$a_{2} = 2 . 2 + 5 = 4 + 5 = 9$
$a_{3} = 2 . 3 + 5 = 6 + 5 = 11$
$a_{4} = 2 . 4 + 5 = 8 + 5 = 13$
$a_{5} = 2 . 5 + 5 = 10 + 5 = 15$
$n_{6} = 2 . 6 + 5 = 12 + 5 = 17$
