Answer:


Step-by-step explanation:

This question asks for the sum of the first 5 terms of the series.

Looking at the first 3 terms, we can see that each successive term is half of the one before it.

<em>So next term after 100 would be 50. Next term after 50 would be 25.</em>


Thus, we can write:

400 + 200 + 100 + 50 + 25 + ...

We already have first 5 terms, the sum is:

400 + 200 + 100 + 50 + 25 = 775

Answer choice B is right.

The correct answer is B) 775 

Why 775? Because Assume the series continues.

400+200+100+50+25=775

I hope this helps. 

Have a great day. :)

What are 3 consecutive numbers that is the sum of -27.please be right.use odd numbers
qaws [65]
You're asking for three consecutive odd numbers, then
Let, the numbers = x, x+2, x+4

It is given that, x + x+2+ x+4 = -27
3x + 6 = -27
3x = -27 - 6
x = -33/3
x = -11
Then, x+2 = -9 & x+4 = -7

In short, Your Numbers would be: -7, -9,-11

Hope this helps!
