Step-by-step explanation:
Deal #1: One pizza= $8.99
Deal #2: One pizza= $6.00
Deal #1: Two pizzas= $13.99
Deal #2: Two pizzas= $12.00
Deal #1: Three pizzas= $18.99
Deal #2: Three pizzas= $18.00
Deal #1: Four pizzas= $23.99
Deal #2: Four pizzas= $24.00
Therefore, after FOUR pizzas, deal #1 becomes a better deal.
Tip: Practice some math. You should be able to answer something like this within two minutes MAXIMUM.
The given sequence is x-1, -2x+2, 4x-4, -8x+8 .
Notice that this is a geometric sequence because here we have equal common ratio.
So, common ratio : r = 
= 
=
Take out -2 as common factor
= -2 Cancel out x - 1.
The formula for general term of a geometric sequence is,

Where, first term: 
We need to find the 10th term of this sequence. So, n = 10.
Next step is to plug in these values in the above formula to get the 10th term. Hence,

So, A is the correct choice.
