2) What is the closed linear form for this sequence given a1 = 13 and an+1 = an * 4?
A)
an = 9+ 4n
B)
an = 9 - 4n
C
an = 13 - 4n
D)
an = 13 + 4n - 1

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
