The sum of 4 consecutive integers is 182. W hat is the sum of the middle two numbers?

Kamila [148]

Answer:

Step-by-step explanation:

Let

x = first number

x+1 = second number

x+2 = third number

x+3 = fourth number

Total = 182

x + x + 1 + x + 2 + x + 3 = 182

4x + 6 = 182

Subtract 6 from both sides

4x + 6 - 6 = 182 - 6

4x = 176

Divide both sides by 4

x = 176 / 4

= 44

x = 44

x+1 = 44 + 1 = 45

x+2 = 44 + 2 = 46

x+3 = 44 + 3 = 47

Sum of the two middle numbers = 45 + 46

= 91

HELP PLZ! THIS IS TIMED.

IgorC [24]

Answer:

$b_n=\dfrac{2}{3}\cdot (9)^{n-1}$

Step-by-step explanation:

Given the geometric sequence

$a_1=\dfrac{2}{3}\\ \\a_n=3a_{n-1},$

then

$a_1=\dfrac{2}{3}\\ \\a_2=3a_1=3\cdot \dfrac{2}{3}=2\\ \\a_3=3a_2=3\cdot 2=6\\ \\a_4=3a_3=3\cdot 6=18\\ \\a_5=3a_4=3\cdot 18=54\\ \\...$

Hence,

$b_1=a_1=\dfrac{2}{3}\\ \\b_2=a_3=6=\dfrac{2}{3}\cdot 9\\ \\b_3=a_5=54=\dfrac{2}{3}\cdot 9^2\\ \\...$

Thus, the explicit formula is

$b_n=\dfrac{2}{3}\cdot (9)^{n-1}$
