Answer 2

Hey, sup!

As per the question,
It can be solved by AP.

a=1.
l=99.
d=2.

T(n)= a+(n-1)d.
=>99= 1+(n-1)2.
=>99-1=(n-1)2.
=>98=(n-1)2.
=>98/2=n-1.
=>49=n-1.
=>n=49+1=50

S(n)=n/2(a+l)
S(50)=50/2(1+99).
= 25*100.
= 2500.

So average= sum of numbers/total number.
= 2500/50=50.

Hope it helps.
