How long will it take for 10% of a 1000-gram sample of uranium-235 to In(0.5)
decay? Use the decay formula A(t) = Age
T
The half-life for uranium-235 is 703,800,000 years.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
