I’m not 100% but from what i know i think it’s (C.)
Answer:
Firstly, we have to transform CHF to 
in order to work with the same currency and make the comparisson:
If 
Then:
Now we can make the comparisons:
a) In Geneva the watch costs 
and in Manchester it costs 
.
According to this:
<h2>In Geneva the watch is cheaper</h2>
b) If we want to know by how much is cheaper, we have to substract from the expensive price the value of the cheaper price:
Therefore:
<h2>The watch in Geneva is
cheaper than the same watch in Manchester.</h2>
You just need to substitute 20 for x and then solve.
a(20) = -5 +(20-1)3
Simplify: a(20) = -5 + (60-3)
Simplify: a(20) = -5 + 57
Result: a(20) = 52
So, 52 is the 20th term of the arithmetic sequence.
