Answer:
Hello, In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
Hope this helped!!
{ 1,-3,9...}
an = a1 * r^(n-1)
a1 = first term = 1
r = common ratio = -3
so ur formula is : an = 1 * -3^(n-1)
Both of these numbers have 2 and 5 as their factors
The second one. 4/6 and 2/3
