Good morning ☕️

Answer:

<h2>U1  = -5</h2><h2>Un = Un-1 + 13  when n≥2</h2><h2 /><h2 />

Step-by-step explanation:

-5, 8, 21, 34, 47, 60

60-47=13

47-34=13

34-21=13

21-8=13

8-(-5)=13

then the common differences q for this arithmetic sequence Un is 13

Then the recursive formula is:

U1 = -5

Un= Un-1 + r  when n≥2

U1 = -5

Un= Un-1 + 13  when n≥2

(-7x² + 3) + (4x² + 2x - 1)

-7x² + 3 + 4x² + 2x - 1          

(-7x² + 4x²) + (3 - 1) + 2x      collect like terms

-3x² + 2x + 2     

hope this helps, God bless!
