Answer:

If there was another dog whose weight was greater than or less than 12.

Step-by-step explanation:

12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 4

When we add 4 to the data set we have:

184 ÷ 16 = 11.5

This changed the median.

12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 28

When we add 28 to the data set we have:

208 ÷ 16 = 13

This also changed the median.

Define a sequence by a1=3 and an=3an−1. Find the first four terms of the sequence. Give a simplified integer answer.

aalyn [17]

Answer:

The first four terms are 3,9,27,81

Step-by-step explanation:

Given first term of sequence is $a_{1} = 3$

Given 'n' t h term is $a_{n} = 3 a_{n-1}$ .............(1)

here we put n = 2 in equation (1)

$a_{2} = 3a_{2-1}$

$a_{2} = 3 a_{1}$ ..............2

put $a_{1} = 3$ in equation (2)

$a_{2} = 3(3)$

$a_{2} = 9$

put n=3 in equation (1)

$a_{3} = 3 a_{3-1}$

$a_{3} = 3a_{2}$

$a_{3} = 3 (9) = 27$

put n= 4 in equation (1)

$a_{4} = 3 a_{4-1}$

$a_{4} = 3 a_{3}$

$a_{4} = 3(27) = 81$

The first four terms of the sequence is

3 , 9, 27 , 81 ....this is geometric sequence

a =3 and ratio term is r =3
