In a parallelogram, diagonals bisect each other. If AO=3, AM=3
Answer:
21, 15
Step-by-step explanation:
12+9=21
the third side of a triangle must be equal to the two other sides added up to make it possible
also 15 if you're trying to make a possible right triangle
31/50 you can’t reduce because 31 is prime
Series is 15, 12, 9…,
Difference between terms is 3
By Arithmetic progression
a_{n}=a_{1}+(n-1)d
a_n = the nᵗʰ term in the sequence
a_1 = the first term in the sequence
d = the common difference between terms
So nth term is a(n) = 15 + (n-1)*3
= 15+ 3n -3
= 12 + 3n
