Write the first three terms in each of the following sequences defined by the following:
$a_{n}=2 n+5$
Write the first three terms in each of the following sequences defined by the following:
$a_{n}=2 n+5$
Here $a_{n}=2 n+5$
Substituting $ n =1,2,3, $ we get
$a_{1} =2(1)+5=7, a_{2}=9, a_{3}=11$
Therefore, the required terms are $7,9$ and $11 .$
