Here is a function that describes a sequence called the Lucas numbers, which is similar to the Fibonacci sequence:
f(n) = f(n-1) + f(n - 2); f(1) = 2; f(2) = 1.
• Describe in words the relationship between the terms created by this algebraic rule.
• List the first six terms of the sequence.
• Find the 12th term.

Can someone me i’m confused. will give brainliest and a whole bunch of points

Solve the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab

Use the following statements to write a compound statement for the conjunction or disjunction. then find its truth value. p: an isosceles triangle has two congruent sides. q: a right angle measures 90° r: four points are always coplanar. s: a decagon has 12 sides. a) a right angle measures 90° or an isosceles triangle has two congruent sides; true. b) a right angle measures 90° and an isosceles triangle has two congruent sides; true. c) a right angle measures 90° and an isosceles triangle does not have two congruent sides; false. d) a right angle measures 90° or an isosceles triangle does not have two congruent sides; true.
