What is the next number in the pattern below? 3, 5, 9, 15, 23, ___ 31 33 35 37
DaniilM [7]
Each term in this pattern is created by adding consecutive multiples of 2 to the previous term.
a_1=3 \\
a_2=3+ 2 \times 1=5 \\
a_3=5+2 \times 2=9 \\
a_4=9+2 \times 3=15 \\
a_5=15+2 \times 4=23

You can write the formula for this pattern as:
\left \{ {{a_1=3} \atop {a_n=a_{n-1}+2(n-1)}} \right.

The next number is 23+2 \times 5=23+10=33.
The answer is 33.

Which expression is equivalent to the given expression?
Inessa05 [86]

Answer:

C

Step-by-step explanation:

Using the rules of logarithms

loga + logb = log(ab)

loga - logb = log(\frac{a}{b} )

logx^{n} ⇔ nlogx

Given

4lnx + ln3 - lnx

= 3lnx + ln3

= lnx³ + ln3

= ln(x³ × 3)

= ln(3x³) → C

Rearrange w= 3(2a + b) - 4 to make a the subject
Angelina_Jolie [31]

Answer:

\boxed{a =  \frac{w}{ 6}  -  \frac{b}{2}  +  \frac{2}{3} }

Step-by-step explanation:

Solve  \: for \:  a:  \\  =  > w=3(2a+b)-4  \\  \\ w=3(2a+b)4 \: is \: equivalent \: to \: 3(2a+b)-4= w:  \\  =  > 3(2a+b) - 4=w  \\  \\ Expand \:  out \:  terms \:  of  \: the  \: left  \: hand \:  side:  \\  =  > (3 \times 2a) + (3 \times b) - 4 = w \\  =  > 6a+3b - 4=w  \\  \\ Subtract  \: 3b  - 4 \:  from  \: both \:  sides:  \\  =  >   6a + 3b - 4 - (3b - 4)=w - (3b - 4) \\   =  > 6a = w - 3b + 4 \\  \\ Divide  \: both  \: sides \:  by  \: 6: \\  =  >  \frac{ \cancel{6}a}{ \cancel{6}}  =  \frac{w - 3b + 4}{6}  \\   =  > a =  \frac{w}{6}  -  \frac{3b}{6}  +  \frac{4}{6}  \\  =  > a =  \frac{w}{ 6}  -  \frac{b}{2}  +  \frac{2}{3}
