Answer:
Step-by-step explanation:
We have total 1200 wildflowers in first year that is first term a is 1200
We have to find sigma notation showing the infinite growth of the wildflowers.

Formula for infinite sum of GP is 
Here, 
On substituting the values in the formula of sum we get:

On simplification we get:

Therefore, total sum of wildflowers 1600.
3x-13=305
3x=305+13
3x=318
(3x)÷3=318÷3
x=106
check.. (3×106)-13=305
318-13=305
305=305
33.2 blah blah blah 20 character 33.2
250 divided by 10 squared is 2.5
