Answer:741
Step-by-step explanation:
Given
First term [tex]a_1=16[/tex]
last term [tex]a_n=98[/tex]
and no of terms [tex]n=13[/tex]
And sum of n terms is given by
[tex]S_n=\frac{n}{2}[a_1+a_n][/tex]
[tex]S_n=\frac{13}{2}[16+98][/tex]
[tex]S_n=\frac{13\times 114}{2}[/tex]
[tex]S_n=13\times 57[/tex]
[tex]S_n=741[/tex]
Sp sum of n terms is 741
