Answer:
AD = 84
Step-by-step explanation:
Since B is the midpoint of AC then AB = BC = 2x - 5
Since C is the midpoint of AD then AC = CD, thus
AB + BC = CD, that is
2x - 5 + 2x - 5 = x + 29
4x - 10 = x + 29 ( subtract x from both sides )
3x - 10 = 29 ( add 10 to both sides )
3x = 39 ( divide both sides by 3 )
x = 13
Hence
AD = AB + BC + CD
= 2x - 5 + 2x - 5 + x + 29 = 5x + 19, thus
AD = (5 × 13) + 19 = 65 + 19 = 84

Answer:

Step-by-step explanation:
An arithmetic sequence is generally given as:
f(n) = a + (n - 1)d
where a = first term and f(n) = nth term, d = common difference
The explicit formula given is:
f(n) = 11 + 22(n - 1)
The recursive formula is made of two statements, the first term and the formula showing how successive terms are related.
Mathematically, it is given as:

Therefore, the recursive formula is:

7x+2x= 54
9x= 54
X=6
Black 7(6)=42
White 2(6)=12
=54
