a) The infinite series in <em>sigma</em> notation is described by this expression:

y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}     (1)

b) The <em>explicit</em> formula for the n-th <em>partial</em> sum is represented by the following expression:

y = \frac{1}{i\cdot (i+2)}, i ∈ \mathbb{N}     (2)

<h3>How to derive an expression for a monotonous series</h3>

An infinite series is <em>monotonous</em> when it is <em>bounded</em>, that is, when the limit of the <em>infinite</em> series exists. In this case, we have an evidence of monotony in the denominators of the terms of the given series. In two consecutive terms, the latter always have a denominator greater than the former.

a) The series in <em>sigma</em> notation is now described below:

y = \sum \limits_{i=1}^{\infty} \frac{1}{i\cdot (i+2)}

b) The <em>explicit</em> formula for the n-th <em>partial</em> sum is defined by the expression within the sum, which is now presented below:

y = \frac{1}{i\cdot (i+2)}, i ∈ \mathbb{N}

SVEN [57.7K]

d = 3 , a₁₂ = 40 and Sx_{100} = 7775

In an arithmetic sequence the nth term and sum to n terms are

<h3>• an = a₁ + (n-1)d</h3><h3>• S_n = \frac{n}{2}[2a + (n-1)d]</h3><h3>where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ = \frac{50}{2}[(2×7) +(99×3)</h3><h3>       = 25(14 + 297) = 25(311)= 7775</h3>

Alekssandra [29.7K]

Answer:

Thermometer reading of the lowest recorded temperature at Oymyakon was -96.2° F

Thermometer reading of the lowest recorded temperature at Prospect Creek was -80° F

Step-by-step explanation:

If the temperature is x° F below 0° F then the thermometer reading is -x° F

It is given that the Lowest temperature recorded at Oymyakon in Russai was 96.2°F below 0°F

So the thermometer reading of the lowest recorded temperature at Oymyakon was -96.2° F

Also it is given that the Lowest temperature recorded at Prospect Creek in Alaska  was 80°F below 0° F

So the thermometer reading of the lowest recorded temperature at Prospect Creek was -80° F
