Answer:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1
Let the breadth of the plot = X
Then,the length of the plot = 30+X
The area of the plot= (l)(b)
=X(30+X)=15000(given)
=30X+X^=15000
=x^+30x-15000=0
Then,solve to the value of x...
Thanks!
