Can I ask uncle how did you get the 25 I don't understand

Dankie Siyabonga... keep them coming uncle👊🏾

Uhm Uncle you made a mistake on finding the value of "c" you could have said a+b+c=5(T1) then substitute 5-15+c=5 therefore c=15
Tn=5n^2-15n+15

Because when I substitute it gives the correct answer👍🏽
