What is the nth term?

kumpel [21]

Let $a_k$ denote the kth term of the sequence. Then

$a_k=a_1+d(k-1)$

where d is the common difference between consecutive terms in the sequence and a₁ is the first term.

The sum of the first n terms is

$S_n=\displaystyle\sum_{k=1}^na_k=a_1+a_2+\cdots+a_{n-1}+a_n$

From the formula for $a_k$ , we get

$S_n=\displaystyle\sum_{k=1}^n(a_1+d(k-1))=a_1\sum_{k=1}^n1+d\sum_{k=1}^n(k-1)$

$S_n=\displaystyle na_1+d\sum_{k=0}^{n-1}k$

$S_n=na_1+\dfrac{d(n-1)n}2$

$S_n=\dfrac n2(2a_1-d+dn)$

So we have $d=-5$ , and $2a_1-d=16$ so that $a_1=\frac{11}2$ .

Then the nth term in the sequence is

$a_n=\dfrac{11}2-5(n-1)=\boxed{\dfrac{21-10n}2}$

Simplify the expression x^5 • x^7

iragen [17]

Answer:

$\Huge\boxed{\mathsf{\Rightarrow X^1^2}}$

Step-by-step explanation:

<h3>TO SOLVE:</h3>

With exponent rule.

<h3>SOLUTIONS:</h3>

First, use exponent rule.

EXPONENT RULE:

$\displaystyle \mathsf{\Rightarrow A^B*A^C=A^B^+^C}}$

$\displaystyle \mathsf{X^5^+^7}}$

Solve.

Add the numbers from left to right.

$\displaystyle \mathsf{7+5=\boxed{\mathsf{\Rightarrow 12}}}}$

$\Rightarrow \Large \boxed{\mathsf{X^1^2}}}$

So, the final answer is x¹².
