Consider the following sequence

wlad13 [49]

Answer:

a₇ = 2.375

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

r = $\frac{-76}{152}$ = $\frac{38}{-76}$ = $\frac{-19}{38}$ = - $\frac{1}{2}$

This indicates the sequence is geometric with nth term

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 152 and r = - $\frac{1}{2}$ , then

$a_{n}$ = 152 $(-\frac{1}{2}) ^{n-1}$ , so

a₇ = 152 $(-\frac{1}{2}) ^{6}$ = 152 × $\frac{1}{64}$ = 2.375

What is the general term of the arithmetic sequence – 32, – 25, –18, –11, …?

Karolina [17]

$a_1=-32\\a_2=-32+7=-25\\a_3=-25+7=-18\\a_4=-18+7=-11\\\vdots\\\\\text{The general term of an arithmetic sequence}\ a_n=a_1+(n-1)d\\\\a_1=-32,\ d=7\\\\\text{Substitute}\\\\a_n=-32+(n-1)(7)\qquad\text{use distributive property}\\\\a_n=-32+(n)(7)+(-1)(7)\\\\a_n=-32+7n-7\\\\\boxed{a_n=7n-39}$
