A chemist measures the temperature in degrees Fahrenheit of a chemical

compound every hour. The temperatures approximate a geometric sequence where

an is the temperature at a given hour, and n is the hour. At hour 4, the temperature is

70 °F and at hour 6 the temperature is 80 °F.

Pls include the value of A1 A4 A6 and r thanks

Step-by-step explanation:

The formula for calculating the nth term of a Geometric Sequence is given as: where n is the number of term, r=common ratio and a=first term.

At hour 4, the temperature is F

.......(i)

At hour 6 the temperature is 80°F.

......(ii)

Solving (i) and (ii) simultaneously

Plugging r into equation (i), we could use (ii) as well,

=57.29

Therefore:
