For each sequence find the first 4 terms and the tenth term
a) n squared +3
b) 2n squared

Step-by-step explanation:

Given that:

a) n³

The first 4 terms are;

let assume n = 1

1³ = 1

if n = 2

2³ = 8

if n= 3

3³ = 27

if n = 4

4³ = 64

So, the sequence is 1, 8, 27, 64

The tenth term of this sequence is: 10³ = 1000

b)

2n²

if the first term is 1

then 2(1)² = 2

if n = 2

2(2)² = 8

if n = 3

2(3)² = 18

if n = 4

2(4)² = 32

So, the sequence is 1, 8, 18, 32

The tenth term will be 2(10)² = 200

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
