If tn=5050 ∴ 5050=8 n +2 ⇒ n =(5048/8)=631

Q. Consider a sequence whose sum to $n$ terms is given by the quadratic function $S_{n} = 4 n^{2} + 6 n$ .
For the given sequence the number 5050 is the

$(101)^{th}$ term

$(636)^{th}$ term

$(656)^{th}$ term

$(631)^{th}$ term

If $t_{n} = 5050$
$∴ 5050 = 8 n + 2 \Rightarrow n = \frac{5048}{8} = 631$
