1) What is the greatest common factor of 48 and 64 ? * 3 points

Given the recursive formula for the geometric sequence \( a_{1}=5, a_{n}=\frac{2}{5} a_{n-1} \), find the second term of the sequence. (1 point) \( a_{2}=\frac{8}{5} \) \( a_{2}=2 \) \( a_{2}=\frac{2}{5} \) \( a_{2}=5 \frac{2}{5} \)

Simplify: \( -2 \sqrt{6}-3 \sqrt{54}+4 \sqrt{2}+3 \sqrt{32}-2 \sqrt{24} \)

Given the recursive formula for the arithmetic sequence \( a_{1}=-5, a_{n}=a_{n-1}+4 \), find the first three terms of the sequence. ( 2 points) \( a_{1}=\square, a_{2}=\square \), and \( a_{3}= \)

El desarrollo de cierta planta descrile una liniea recta que pasa por los puntos A \( (2,1) \) y B( 4,3\( ) \), entonces se puede conchur que la planta esta: (A) detentida. (B) decreciendo. (C) constanke. (D) creclendo.

Simplify the expression. \( -19+\left(\frac{-4.5+6.87}{3}\right) \cdot 5^{2}-7.3 \)
