Determine o 15* termo da PA (6, 10, ...)

Qual é o 50* número ímpar positivo

Lista de comentários

Danndrt Para encontrar qualquer termo de uma PA, usamos a fórmula do termo geral:

$a_{n} =a_{1} + (n-1).r$

Temos que:

an = a15
n = 15
a1 = 6
r (razão) = 10 - 6 = 4

Substituindo na fórmula:

$a_{15} =6 + (15-1).4 \\ \\ 
a_{15} =6 + 14.4 \\ \\ 
a_{15} =6 + 56 \\ \\
\boxed{\boxed{a_{15} =62}} \\ \\$

______________

Devemos encontrar o termo a50, em uma PA (1, 3, 5, ...) , sequência dos números ímpares.

Assim,

an = 150
n = 50
a1 = 1
r = 3 - 1 = 2

Substituindo:

$a_{05} =1 + (50-1).2 \\ \\ 
a_{50} =1 + 49.2 \\ \\ 
a_{50} =1 + 98 \\ \\
\boxed{\boxed{a_{50} =99}} \\ \\$
