Step-by-step explanation:
Explanation:-
<u>Geometric sequence</u>:-
The geometric sequence is of the form
……… be an infinite sequence
here first term is 'a' and ratio is 'r '
In this geometric sequence 'n' t h term is ....(1)
Given data a1 term is '8 ' and ratio is '4'
substitute n=1 in equation(1)
= 8
...........(2)
substitute r= 4 in equation(2)
now we get a(4)=8
dividing "4" on both sides , we get a = 2
<u>Geometric series</u>:-
.....is an infinite geometric series.
sum of this infinite series will be the upper limit of the fungal spores
that is we have to find sum of infinite series
<u>Final answer:</u>-
sum of this infinite series will be the upper limit of the fungal spores
