In mathematics, number sequencing of the same pattern are called progression. There are three types of progression: arithmetic, harmonic and geometric. The pattern in arithmetic is called common difference, while the pattern in geometric is called common ratio. Harmonic progression is just the reciprocal of the arithmetic sequence.
The common ratio is denoted as r. For values of r<1, the sum of the infinite series is equal to
S∞ = A₁/(1-r), where A1 is the first term of the sequence. Substituting A₁=65 and r=1/6:
S∞ = A₁/(1-r) = 65/(1-1/6)
S∞ = 78

<h2><u>
Answer:</u></h2>
150.7
<h2><u>
Step-by-step explanation:</u></h2>
To solve this, we first turn both the fractions into decimals :
(add this to 426 to get <u>426.2</u>)
(add this to 275 to get <u>275.5</u>)
Then, just solve the equation :
426.2 - 275.5 = <u>150.7</u>
The <em>correct answers</em> are:
40 songs;
48 songs; and
56 songs.
Explanation:
Since each class sings 8 songs per week, to find the number of songs for any given number of weeks, we multiply:
8 songs per week * 5 weeks = 40 songs
8 songs per week * 6 weeks = 48 songs
8 songs per week * 7 weeks = 56 songs
