What is the common difference, d, in the arithmetic sequence defined by the formula below? an=2n+1

marishachu [46]

<h3>Answer:</h3>

d = 2

<h3>Solution:</h3>

We are given that the arithmetic progression is defined by :

➝ 2n + 1

Therefore, 

For first term

➙ n = 1

➝ 2 × 1 + 1

➝ 2 + 1

➝ 3

For second term

➙ n = 2

➝ 2 × 2 + 1

➝ 4 + 1

➝ 5

Common difference

➙ 2nd term - 1st term

➝ 5 - 3

➝ 2

<h3>More information:</h3>

The difference between the successive term and the preceding term is the difference of an arithmetic progression. It is always same for the same arithmetic progression.

What is the volume of a pyramid 4 cm,4 cm by 12 cm

Alenkinab [10]

Answer:

The volume of pyramid with dimensions 4cm , 4cm by 12cm is $\bold{64 \mathrm{cm}^{3}}$

Solution:

Volume of a pyramid can be found out by using the below formula,

$\bold{v = \frac{1}{3} l w h}$

where,

v is the volume of pyramid

l is the length of pyramid

w is the width of pyramid

h is the height of pyramid

from question, given that l = 4 ; w = 4; h = 12

hence the volume of pyramid for the given dimensions is

$v = \frac{1}{3} \times 4 \times 4 \times 12$

$= 4 \times 4 \times 4$

$= 64 \mathrm{cm}^{3}$

So the volume of pyramid is $\bold{64 \mathrm{cm}^{3}}$
