Answer:
So x = 20
Step-by-step explanation:
AB + BC = AC sum of a segment is sum of its pieces
AB + AB = AC B is the midpoint, so AB = BC
2x + 2x = 3x + 20 putting in for AB (twice!) and AC
4x = 3x + 20 collect like terms
x = 20 subtract 3x on both sides.

This is my answer. Good luck!
Answer:
28 - 4n
Step-by-step explanation:
What is the recursive formula for this sequence? 24,20,16,12
the sequence first term is 24
a= 24
Common difference (d) = T2 - T1 = T3 - T2
d = 20-24 = 16 -20
d = -4
Formula for nth term
Tn = a + (n-1)d
Tn = 24 + (n -1)-4
Tn = 24 -4n + 4
Tn = 28 - 4n
= 28 - 4n
