To find the answer, we can first find the total number divisible by 7 of 50 and 500 separately:

50÷7 = 7.14...

there are 7 divisible for 50.

500÷7= 71.42...

there are 71 divisible for 500.

We can then deduct the number of divisible for 50 from 500 to find the answer:

71-7

=64

Therefore, the answer is 64.

Hope it helps!

Which choice is the explicit formula for the following geometric sequence?0.5, -0.1, 0.02, -0.004, 0.0008, ...

Minchanka [31]

$a_1=0.5\\a_2=-0.1\\a_3=0.02\\a_4=-0.004\\a_5=0.0008\\\\a_n=a_1\cdot q^{n-1}\\\\q=a_2:a_1\to q=-0.1:0.5=-0.2\\\\a_n=0.5\cdot(-0.2)^{n-1}=0.5\cdot(-0,2)^n\cdot(-0.2)^{-1}\\\\=0.5\cdot(-0.2)^n\cdot(-5)=-2.5\cdot(-0.2)^n\\\\\boxed{a_n=-2.5\cdot(-0.2)^n}$
