789 is a repeating decimal
A=9
b=7
c>a-b
c>2
c<a+b
c<7+9
c<16
⇒c∈(2,16)
⇒ The correct answer is A,B,C,E
As we can see it's a geometric progression.
q = a2/a1
q = 1/3
so,
an = a1 . q^(n - 1)
an = 3 . (1/3)^(n - 1)
The one which matches is f(n) = 3 . (1/3)^(n - 1)
Alt C.
Answer:
16 cm2
Step-by-step explanation:
thats the answer
First term = 3
multiplier = 0.25
second term = 3 * (1/4)
third term = 3 * (1/4)^2
fourth term = 3 * (1/4)^3
fifth term = 3 * (1/4)^4
Can you simplify the fifth term?
