Answer:
aₙ= 3n+1
Step-by-step explanation:
4 ,1 -2, -5 ,-8
AP with a₁=4 and d= -3
----------------
aₙ= 4+3*(n-1)= 4+3n-3= 3n+1
aₙ= 3n+1

The true equations are 24 over 2 squared equals 50 minus 6 squared minus 8 and 56 divided by 8 plus 3 squared equals 2 times 2 cubed.
The equation one is given as
39- 3(6) = 6(10/4)+4
After solving we get,
39 - 18 = 15 +4
21 = 19
Which is not a true equation.
2nd equation we have
24/(2^2)=50 -6^2-8
24/4 = 50 -36 -8
6 = 50 - 44
6 = 6
which is a true equation.
3rd equation we have
56/8+3^2= 2(2^3)
7 +9 = 2(8)
16 = 16
which is true equation.
4th equation, we have
8^2-5^2 = 4^2-7
16-10 = 16-7
6 = 9
Which is not a true equation.

If the plant grows 2h what ????
A linear pair is a pair of adjacent, supplementary angles which sum is equal 180
So
5x + 5 + 11x - 65 = 180
16x - 60 = 180
16x = 240
x = 15
<PQR = 5(15) + 15 = 75 + 5 = 80
Answer
80°
