Answer:
x,y
Step-by-step explanation:
because it shows range and dange
Answer:
the first term is a1
the distance between the numbers is d
we have:
a5 = a1 + 4d = 23
a12 = a1 + 11d = 72
so we have the equation:
a1 + 4d = 23
a1 + 11d = 72
=> a1 = -5
d = 7
=> an = -5 + 7(n - 1) = 7n - 12
with an = 7n - 12
=> a2 = 2
a3 = 9
so the first three terms is -5; 2; 9
<span>P(n,2)=42, find n.
------------
n!/(n-2)! = 42
n(n-1) = 42
n^2 -n - 42 = 0
(n-7)(n+6) = 0
Positive answer:
n = 7
