.05/5=.5/5=1/10 so the common ratio is 1/10 and the first term is 5.
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number so this sequence is:
a(n)=5(1/10)^(n-1) (the bottom answer)
£54 / 10 = £5.40
£5.40 x 4 = £21.60
£54+£21.60 = £75.60

The answer is C) A relationship between two quantities in which the ratio of one quantity to the other quantity is constant.
In other words,
The constant of variety is the number that is is comparable to two variables that are straightforwardly corresponding or contrarily corresponding to each other.
The future value of her investment will be
.. 3000*(1.1^35 -1)/(1.1 -1) ≈ 813,073.11
That supports 30 years of annual payments of
.. 813,073.11*(.1)/(1 -1.1^-30) = 86,250.18
