Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.
You can use 27 $10 bills which gets your at a total of $270 then you can use 1 $5 bill so now you're at $275 then you can use 4 $1 bills that gets you at your total of $279. The least number of bills you can use is 32.
