Oorweeg die getalpatroon: 3.1.1 Toon aan dat hierdie reeks getalle 'n lineêre getalpatroon voorstel. 3.1.2 Bepaal die algemene reēl \( \left(T_{n}\right) \) van hierdie getalpatroon. 3.1.3 Bepaal watter term in die getalpatroon gelyk sal wees aan -61. 3.1.4 Bepaal \( T_{5} \) 3.1.5 Bepaal \( T_{5} \) en \( T_{55} \).

-11) \( \frac{22^{4} \cdot 8^{4}}{121^{4} \cdot 4^{6}}= \)

9. Use any method to solve the system: \( \left\{\begin{array}{c}x^{2}+y^{2}=9 \\ 9 x^{2}+4 y^{2}=36\end{array}\right. \)

3. \( 3 x(4 x-5) \)

QUESTION 3 3.1 Given the number pattern \( 2 ; y ; 8 ; \ldots \) Determine the value of \( y \) if: 3.1.1 The number pattern is linear. 3.1.2 The number pattern is quadratic and \( T_{4}=2+5 y \). 3.2 In a linear number pattern, the \( 19^{\text {th }} \) term is 40 and the \( 7^{\text {th }} \) term is 16 . Thus, determine the first two terms. 3.3 The general term of a quadratic number pattern is \( T_{n}=n^{2}+2 n-15 \). Determine which term has a value of 20 .

\( 19 j-86 \geq 5 \) or \( 27 j-82 \leq 18 \)
