Step-by-step explanation:
r=14/7=28/14=56/28=2
So it is geometric
By using this equation:
a(n)=a1*(r)^(n-1)
and we have a(1)=7 , r=2
<u>explicit equation : a(n)=7*(2)^(n-1)</u>

Answer:
Step-by-step explanation:
E : -5 , -3
F: 2 , -7
Distance = sqrt( ( 2 -(-5)) * ( 2 -(-5)) + (-7 -( -3)) *(-7 -( -3)) )= sqrt ( 49 + 16 ) = sqrt (65)
Answer:
