Question
Bacteria quadruples on a daily basis. The population starts with 50 bacteria. Using the general exponential equation an=a1⋅rn−1
, what value would represent a1
?(1 point)
The value of a1
is
.

1 answer

In a geometric sequence, \( a_1 \) represents the first term of the sequence. In the case of the bacteria population that starts with 50 bacteria, the initial population is the first term of the sequence.

Thus, the value of \( a_1 \) is:

\[ a_1 = 50 \]
