Step-by-step explanation:
supplementary angles add to 180° 2 + 3, 3 + 4
complementary angles add to 90° 1 + 2
Hi,
(9n + 4) - (-12n - 7)
9n + 4 + 12n + 7
<em>=</em><em> </em> 21n + 11

Answer:
4/9
Step-by-step explanation:
Finally, I can put my answer!
Answer: aₙ = 3 + 4ⁿ⁻¹
So the formula would be:
<u>aₙ = 3 + 4ⁿ⁻¹</u>
Where a₁ = 3
Common Ratio (r) = 4
And n = the term number that needs to be found out
Step-by-step explanation:
<u>Let's check if the answer is right:</u>
To find the 1st number in the term we can substitute 1 in for n in the equation:
a₁ = 3 + 4¹⁻¹
a₁ = 3 + 4⁰
a₁ = 3 + 1
a₁ = 4
And if going back and checking the first number in the sequence given is indeed 4, therefore this equation is correct
Hope this helps!
