Answer:
First five terms are (5, 7, 9, 11, 13)
Step-by-step explanation:
[tex]a_n = 5+(n-1)2[/tex]
Arithmetic explicit rule is given we need to find first five terms.
Let n be number of terms.
When n = 1,
[tex]a_1= 5+(1-1)2= 5+(0)2=5[/tex]
When n = 2,
[tex]a_2=5+(2-1)2=5+2=7[/tex]
When n = 3,
[tex]a_3=5+(3-1)2=5+4=9[/tex]
When n = 4,
[tex]a_4=5+(4-1)2=5+6=11[/tex]
When n = 5,
[tex]a_5=5+(5-1)2=5+9=13[/tex]
Hence the First five terms are (5, 7, 9, 11, 13)
