Asequence {un) is given by the recurrence relation anti un+1 = un + att for n= 1,2,3, and the initial term ui = 3. (a) showing your working, use the recurrence relation to compute un for n = 2,3,4,5. (b) give a proof by induction to show that un= 2 - (n + 2)2-" for all n 2 1.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

42
