TMUA Practice Question

The positive integers are written in order in rows. Row 1 is the single integer $1$, and each row after that contains two more integers than the row before: $$\begin{array}{ccccccc}& & & 1& & & \\ & & 2& 3& 4& & \\ & 5& 6& 7& 8& 9& \\ 10& 11& 12& 13& 14& 15& 16\\ & & & ⋮& & & \end{array}$$ What is the sum of the integers in row $10$?
