-6 [4-(x-2)]
Distribute.
-6-4x+2
-4x-4
Answer:
an =
Step-by-step explanation:
Explicit rule for Geometric series is given by
Here a is the first term and r is the common ratio.
in our question first term a =
common ratio r = 2
therefore explicit rule an =
or
an=
(28) 2x+10+x-4=21
(29) 3x-16+4x-8=60
(30) 2x-8+3x-10=17
Answer: 4
Step-by-step explanation:
However, as the base must be positive, n=4.
