Help on math! First correct answer will get brainliest answer

Let's look at the terms of the sequence for different values of n, starting from 0.

a₀ = 0/1 = 0

a₁ = 1/(1 +1) = 1/2

a₂ = 2/(2 + 1) = 2/3

a₃ = 3/(3 + 1) = 3/4

a₄ = 4/5

a₅ = 5/6

a₆ = 6/7

a₇ = 7/8

a₈ = 8/9

a₉ = 9/(9+1) = 9/10

a₁₀ = 10/(10+1) = 10/11 and so on

Let's look at the terms. As n gets bigger the terms gets closer to 1. We started with 0, then to one half, then two thirds, and as we get larger and larger, the terms are getting closer to 1. Let's choose a really big n and see.

a₉₉₉ = 999/(999 + 1) = 999/1000

Or an even bigger n:

a₉₉₉₉₉₉₉₉₉ = 999999999/(999999999 + 1) = 999999999/1000000000ⁿ

So as n gets really really large - and close to infinity - the terms get closer to 1.

Which comparison is correct?
r-ruslan [8.4K]

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is the correct answer.

Explanation:

Option A: $7.1 \times 10^{8}>1.2 \times 10^{9}$

Simplifying, we get,

710000000>1200000000

Since, the value of $1.2 \times 10^{9}$ is greater than $7.1 \times 10^{8}$, the comparison $7.1 \times 10^{8}>1.2 \times 10^{9}$ is false.

Hence, Option A is not the correct answer.

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$

Simplifying, we get,

0.0000045>0.0000000039

Since, the value of $4.5 \times 10^{-6}$ is greater than $3.9 \times 10^{-9}$, the comparison $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is true.

Hence, Option B is the correct answer.

Option C: $2.4 \times 10^{-5}

Simplifying, we get,

0.000024

Since, the value of $2.4 \times 10^{-5}$ is greater than $5.7 \times 10^{-6}$, the comparison $2.4 \times 10^{-5} is false.

Hence, Option C is not the correct answer.

Option D: $8.2 \times 10^{-4}

Simplifying, we get,

0.00082

Since, the value of $8.2 \times 10^{-4}$ is greater than $3.6 \times 10^{-6}$, the comparison $8.2 \times 10^{-4} is false.

Hence, Option D is not the correct answer.
