Perform the modular arithmetic.(19 − 8) text{mod} 7

Write A if the sequence is arithmetic, G if it is geometric, H if it is harmonic, F if Fibonacci, and O if it is not one of the mentioned types. Show your Solution. a. $\frac{1}{3},\frac{2}{9},\frac{3}{27},\frac{4}{81},...$ b. $3,8,13,18,...,48$

Compute $$(11-8)\times 10÷14\times 12-5$$.

Is the sequence $-2,-1,-\frac{1}{2},-\frac{1}{4},\cdots$ geometric? If so find the common ratio. If not, explain why

Arithmetic or Geometric?
a) If ${\displaystyle a_1,a_2,a_3,\cdots }$ is an arithmetic sequence, is the sequence ${\displaystyle a_1+2,a_2+2,a_3+2,\cdots }$ arithmetic?
b) If ${\displaystyle a_1,a_2,a_3,\cdots }$ is a geometric sequence, is the sequence ${\displaystyle 5a_1,5a_2,5a_3,\cdots }$ geometric?

What is the derivative of the function
${\displaystyle f\left(x\right)=\frac{3x-5}{5x+2}}$?

A sequence is shown below.
28,56,112,224.
Which statement is true?
A) Thesequence is arithmetic because the difference between the numbers is constant.
B) The sequence is arithmetic because the numbers are being multiplied by 2.
C) The sequence is geometric because the numbers are beign multiplied by 2.
D) The sequence is geometric because the difference between the numbers is constant.

Perform the operations in the correct order: $$9\times 8÷(13-11)÷11÷11$$.
