A formula for finding the terms of a sequence is shown below. LaTeX: a_1=100a 1 = 100

LaTeX: a_n=\frac{1}{2}a_n-1a n = 1 2 a n − 1
Which formula represents the same sequence?

A. LaTeX: a_n=100\left(\frac{1}{2}\right)^na n = 100 ( 1 2 ) n

B. LaTeX: a_n=100\left(\frac{1}{2}\right)^{n- 1}a n = 100 ( 1 2 ) n − 1

C. LaTeX: a_n=200\left(\frac{1}{2}\right)^{n+ 1}a n = 200 ( 1 2 ) n + 1

D. LaTeX: a_n=200\left(\frac{1}{2}\right)^{n- 1}a n = 200 ( 1 2 ) n − 1

Group of answer choices

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
