i need help with this Arithemetic progression question

Given:-
[imath]a = 7[/imath]
[imath]t_n = 84[/imath]
[imath]t_{3n} = 245[/imath]

Formula to use:-
[imath]t_n = a + (n-1)d[/imath]

Solution:-

Form two equations with two pieces of information given in the question
[imath]7 + (n-1)d = 84[/imath]
[imath]7 + (3n-1)d = 245[/imath]

Now, we have two equations with two unknowns, we can solve them! Making d the subject and equating both equations:-
[imath]\rarr \frac{77}{n-1} = \frac{238}{3n-1}[/imath]
[imath]\rarr 77(3n-1) = 238(n-1)[/imath]
[imath]\rarr 231n - 77 = 238n - 238[/imath]
[imath]\rarr 7n = 161[/imath]

Hence,
[imath]\therefore n = 23[/imath]

So I had this question right? It was if I had a decimal, what was it in radains? I shined a light on the problem, but it did not become radiant? For some reason CHatGPT talked about pie when asked? He wanted 2 pies? Am I stupid or does chatGPT sound more like my mother?
