Answer:

The first three terms are [tex]3,6,11[/tex]

The 10th term is [tex]102[/tex]

Step-by-step explanation:

An ordered list of numbers is known as a sequence such that each number in the sequence is called a term.

The nth term is [tex]a_n=n^2+2[/tex].

To find the first 3 terms, put [tex]n=1,2,3[/tex]

[tex]a_1=1^2+2=1+2=3\\a_2=2^2+2=4+2=6\\a_3=3^2+2=9+2=11[/tex]

To find the 10th term, put [tex]n=10[/tex] in [tex]a_n=n^2+2[/tex]

[tex]a_{10} =(10)^2+2=100+2=102[/tex]
