I need help with #40 ASAP…please help me this one…. Show step by step please

Answer:
22801
Step-by-step explanation:
#40
No. of terms = (301 + 1)/2
No. of terms = 302/2
No. of terms = 151
Now,
Sum = n²
Sum = (151)²
Sum = 22801
Answer:
For #40.
S = 22801
Step-by-step explanation:
On #40 the last term is 301, so we add 1
[tex]302[/tex] ÷ [tex]2 = 151[/tex]
[tex]n = 151[/tex]
To get [tex]n^{2}[/tex], multiply 151 by itself
[tex]151[/tex] × [tex]151 = 22801[/tex]
[tex]S = 22801[/tex]
