The mean is equal to the sum (18) divided by the number of numbers added (7). 18/7 is about 2.5714
The median is the number that is in the middle when ordered from least to greatest (2)
The mode is the number that occurs most often (2)

Find an equation for the nth term of the arithmetic sequence.

amm1812

Answer:

$a_n=-301 +37(n-1)$

Step-by-step explanation:

arithmetic sequence formula: $a_n=a +(n-1)d$

where $a$ is the first term and $d$ is the common difference

Given:

$a_{10}=32$

⇒ $a +(10-1)d=32$

⇒ $a+9d=32$

Given:

$a_{12}=106$

⇒ $a +(12-1)d=106$

⇒ $a+11d=106$

Rearrange the first equation to make $a$ the subject:

a = 32 - 9d

Now substitute into the second equation and solve for $d$

(32 - 9d) + 11d = 106

⇒ 32 + 2d = 106

⇒ 2d = 106 - 32 = 74

⇒ d = 74 ÷ 2 = 37

Substitute found value of $d$ into the first equation and solve for $a$ :

a + (9 x 37) = 32

a + 333 = 32

a = 32 - 333 = -301

Therefore, the equation is: $a_n=-301 +37(n-1)$

Arithmetic and geometric series -Find the sum of the first 50 terms of the following series, to the nearest integer.

grandymaker [24]

Answer:

Step-by-step explanation:

21-13=8 and 29-21=8

So this is aritmetic series where a₁ = 13, and r = 8

Sum of the first n terms:

$S_n=\dfrac{a_1+a_n}{2}\cdot n=\dfrac{a_1+a_1+(n-1)r}{2}\cdot n=\dfrac{2a_1+(n-1)r}{2}\cdot n\\\\\\S_{50}=\dfrac{2\cdot13+(50-1)\cdot8}{2}\cdot50=(13+49\cdot4)\cdot 50=10,450$

Given logx 2=p and logx 7=q , express log7 4x² in terms of p and q

kodGreya [7K]

Answer:

[2(p + 1)]/q

Step-by-step explanation:

logx 2 = p

logx 7 = q

log7 4x² = log7 (2x)²

= (logx (2x)²)/(logx 7)

= (2 logx 2x)/(logx 7)

= (2 logx 2 + 2 logx x)/(logx 7)

= (2p + 2)/q

= [2(p + 1)]/q
