) \( x^{2}+(y-3)=38^{2} \)

\( y \mp - 2 x + 5 \)

The first, second and fourth term of a given sequence are \( 11-x, 2 x+1 \) and \( 3 x+1 \). [ 3 marks ] a) Calculate the value of \( x \). [ 4 marks ] b) Find the sum of the first twelve terms of the sequence. [ 2 marks ]

Sea \( A=\left[\begin{array}{llll}2 & 0 & 3 & 1 \\ 0 & 1 & 4 & 2 \\ 0 & 0 & 1 & 5 \\ 1 & 2 & 3 & 0\end{array}\right] \) Encontrar: a) \( \operatorname{det}(A) \)

2) \( \frac{10 x-8}{4}=\frac{1}{4} \)
