common ratio is 2
first term is 7
last option is the answer
This is a geometric sequence, since each term is found by multiplying the previous term by 2.
The explicit formula for a geometric sequence is given by
, where a₁ is the first term and r is the common ratio, and n is the term number.
For our sequence, the first term is 7. The common ratio is 2. This gives us
Since we want the 10th term,
the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.
brand = spend $ 135.85 total
store = spend $80.07 total
