A) A sequence is defined using this term-to-term rule. Un+1 2un+ 20
If u1 = 8, find uz
b) Another sequence is defined using this term-to-term rule,
Un+1 = kun +r
where k and rare constants.
Given that uy = 37, uz = 188 and uz = 943, find the value of k and
the value of r.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
