Answer:

So the sequence will be 4, 8, 16, 32, 64, 128 .......

Step-by-step explanation:

We have to graph the first six terms of a sequence with first term a = 4 and r = 2 Since r denotes common ratio so the given sequence is a geometric sequence.

Now we know the explicit formula for a geometric sequence is

T_{(n)}=a(r)^{n-1}

Since   T_{1} = 4

So        T_{2}=4(2)^{2-1} = 4 × 2 = 8

            T_{3}=4(2)^{3-1} = 4 × 2² = 4 × 4 = 16

           T_{4}=4(2)^{4-1} = (4)(2)^{3} = 4 × 8 = 32

           T_{5}=4(2)^{5-1} = 4(2)^{4} = 4 × 16 = 64

           T_{6}=4(2)^{6-1} = 4(2)^{5} = 4 × 32 = 128

So the sequence will be 4, 8, 16, 32, 64, 128 .......

How to get answer for number 1: | 4+2i |

\left|a+bi\right|\:=\sqrt{\left(a+bi\right)\left(a-bi\right)}=\sqrt{a^2+b^2}\\\mathrm{With\:}a=4,\:b=2\\=\sqrt{4^2+2^2}\\Refine\\=\sqrt{20}\\\sqrt{20}=2\sqrt{5}\\=2\sqrt{5}

How to get answer for number 2: | 5-i |

\left|a+bi\right|\:=\sqrt{\left(a+bi\right)\left(a-bi\right)}=\sqrt{a^2+b^2}\\\mathrm{With\:}a=5,\:b=-1\\=\sqrt{5^2+\left(-1\right)^2}\\=\sqrt{26}

Number 3 how to get answer: | -3i |

\left|a+bi\right|\:=\sqrt{\left(a+bi\right)\left(a-bi\right)}=\sqrt{a^2+b^2}\\\mathrm{With\:}a=0,\:b=-3\\=\sqrt{0^2+\left(-3\right)^2}\\Refine\\=\sqrt{9}\\\sqrt{9}\\\mathrm{Factor\:the\:number:\:}\:9=3^2\\=\sqrt{3^2}\\\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a\\\sqrt{3^2}=3\\= 3
