Sequence One
Step-by-step explanation:
S = a₁ / (1 − r) is the infinite sum of a geometric series where |r| < 1.
Sequence One: r = 1/5
Sequence Two: r = 2
Sequence Three: not geometric
Sequence Four: r = -3/2
Only Sequence One has |r| < 1.

Answer:
The age of the spear head to the nearest year is 1845 years
Step-by-step explanation:
We know that
half life time of C-14 is 5730 years
so, h=5730
we can use formula

now, we can plug value

an archaeologist in turkey discovers a spear head that contains 80% of its original amount of C-14
so,

we can plug it

now, we can solve for t




So,
The age of the spear head to the nearest year is 1845 years
