We have the sequence 2, 6, 10, 14, 18, ... Always 4 being added, so we can say:
The first term is 2. The added is 4, so,
a1 = 2

Prove:

Answer:
Step-by-step explanation:
Answer:
It will take 50 years to decay from 512 grams to 121.5 grams.
Step-by-step explanation:
The decay formula :

where
N= amount of substance after t time
N₀= initial of substance
t= time.
A substance decays at a rate 25% every 10 years.
So, remaining amount of the substance is = (100%-25%)= 75%
, t= 10



Taking ln both sides



Now , N₀= 512 grams, N= 121.5 grams, t=?




Taking ln both sides




⇒t=50 years
It will take 50 years to decay from 512 grams to 121.5 grams.
I'm pretty sure its neither just substitute the x for -2 and solve. There has to be a consistency in the values 3 times for there to be a pattern.
