How many of the first 200 positive integers are multiples of neither 6 nor 15
1 answer:
There are
.. floor(200/6) = 33 multiples of 6
in the range 1 .. 200.
There are
.. floor(200/15) = 13 multiples of 15
in the range 1 .. 200, half of which are also multiples of 6.
So, there are 33 +13 -6 = 40 numbers in the range 1 .. 200 that are multiples of either 6 or 15 or both.
The remaining 200 -40 = 160 numbers are not multiples of either.

Answer:
B
Step-by-step explanation:
The common ratio r exists between consecutive terms in the sequence, that is
r = - 62.5 ÷ 12.5 = 312.5 ÷ - 62.5 = - 1562.5 ÷ 312.5 = - 5
18x-2+12x+2=180
30x=180
x=180:30
x=6
