2,5,8,11,14 write down in terms of n , an expression for the nth term for this sequence

Mathematics
1 answer:
Alisiya [41]3 years ago

Answer:

a_{n} = 3n - 1

Step-by-step explanation:

Note there is a common difference d between consecutive terms in the sequence, that is

5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 3, thus

a_{n} = 2 + 3(n - 1) = 2 + 3n - 3 = 3n - 1

Find the volume of a cube where the length of each side is 6 centimeters.
notka56 [123]
Well if each side is 6cm each then u Have to multiply 6x how many sides to the cube there are. So if there are 6 sides to a cube and you have 6cm each side then you have to multiply 6cm X 6 witch = 36 then multiply 36X6=216. So the final answer is 216. 

Hope this helps!

7 5/6 - 3 1/12 what does this equal as a fraction in simplest form
KengaRu [80]

For this case we convert the mixed numbers into fractions:

7 \frac {5} {6} = \frac {6 * 7 + 5} {6} = \frac {42 + 5} {6} = \frac {47} {6}\\3 \frac {1} {12} = \frac {12 * 3 + 1} {12} = \frac {36 + 1} {12} = \frac {37} {12}

Rewriting the expression:

\frac {47} {6} - \frac {37} {12} =\\\frac {12 * 47-6 * 37} {6 * 12} =\\\frac {564-222} {72} =\\\frac {342} {72} =

We simplify:

\frac {171} {36} =\\\frac {57} {12} =\\\frac {19} {4}

Thus, the simplified form is:\frac {19} {4}

Answer:

\frac {19} {4}

WILL GIVE BRAINLIEST IF RIGHT AND WORTH 75 POINTS
drek231 [11]

Answer: Team one = 1/5

Team 2 = 4/21

Team A is the fastest

Step-by-step explanation: Answer: Team one = 1/5

Team 2 = 4/21

Team A is the fastest

Step-by-step explanation: TEAM A

Tammy working alone in 1hr can clean 1/2

Melissa working alone in 1 hr  can clean 1/3

working together in 1hr ,let x represent the area they will clean  we have

\frac{1}{1/2} + \frac{1}{1/3} = 1/x

⇒ 3 + 2 = 1/x

5 = 1/x

x = 1/5

TEAM B

Santay working alone can clean  1/4

Leticia working alone in 1 hr can clean 4/5

working together in 1 hr ,let y represent the amount they clean,  we have

\frac{1}{1/4} + \frac{1}{4/5} = 1/y

4 + 5/4 = 1/y

21/4 = 1/y

y = 4 /21

comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
