Find The Common Difference In The Arithmetric Sequence 3,13/4,7/2,15/4

Find the common difference in the arithmetric sequence 3,13/4,7/2,15/4

 

Answer:

d= -1/4

Step-by-step explanation:

d=a2-a1 or d=a3-a2

3-\frac{13}{4} \\d=\frac{3}{1}-\frac{13}{4} \\d=\frac{12}{4} -\frac{13}{4}\\d=\frac{-1}{4}

Noong 1963, nakamit ng Singapore ang kalayaan mula sa United Kingdom, at nakita mula rito ang dibersidad ng mga kultura sa lugar. Maraming mga taga Malaysia, Tsina at India ang lumipad patungong Singapore upang magtrabaho. Dahil dito, nagkaroon ng mpagsasama ng mga kulturang Tsino, Malay at Islamiko. Sa Edukasyon naman, ang Singapore ay mayroong tatlong lebel, primary, secondary at tertiary, lahat ay sinusuportahan ng pamahalaan. Bawat paaralan, ke pampubliko man o hindi, ay kailangang magparehistro sa Minsitri ng Edukasyon.  Lahat ng mga Singaporean schools ay ginagamit ang Ingles bilang pangunahing wika sa pagtuturo ngunit hindi nalilimutan ang mga bernakulo.  Lahat ng mga Singaporeans ay required mag-aral sa Primary na tumatagal ng anim  na taon. Apat na taon dito ay...

What Is The Meaning Of Conics?

What is the meaning of conics?   Answer: Conics is a branch of Mathematics that it is concerned with Conic Sections.  It is a set of all points P in a plane such that the distance of P from a fixed point is in a constant ratio to the distance of P from a fixed line which does not  contain the fixed point. Conics can find on cones. Step-by-step explanation: There are 4 conic sections: a. Circle - x² + y² = 1 (at the origin); (x-h)² + (y-k)² = 1 (not at the origin) b. Ellipse - x²/a² + y²/b² = 1 (horizontal axis); x²/b² + y²/a² = 1 (vertical axis) c. Parabola - y² = 4px); where the vertex is at the origin, focus at (0,p), directrix at y=-p (x-h)² = 4p (y-k); where the vertex at (h,k), the focus at (h, k+p), and the directrix at y=k-p d. Hyperbola - x²/a² - y²/b² = 1 where the length of the transverse axis is  2 a the coordinates of the vertices are  ( ± a , 0 ) the length of the conjugate axis is  2 b the coordinates of the co-vertices are  ( 0 , ± b ) the distanc...

What Is The Meaning Of Innovation?

What is the meaning of innovation?   Answer: Innovation in its modern meaning is "a new idea, creative thoughts, new imaginations in form of device or method".1 Innovation is often also viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs.2 Such innovation takes place through the provision of more-effective products, processes, services, technologies, or business models that are made available to markets, governments and society. An innovation is something original and more effective and, as a consequence, new, that "breaks into" the market or society.3 Innovation is related to, but not the same as, invention,4 as innovation is more apt to involve the practical implementation of an invention (ie new / improved ability) to make a meaningful impact in the market or society,5 and not all innovations require an invention. Innovation oftenquantify manifests itself via the engineering process, when th...
