Question

Find the next 3 terms of the given rule form

1.An = 4n – 5
2.An = 2n
3.An = 3n + n²
4.An = n/3
5.An = 2n (n–2)​

Answer 1

Step-by-step explanation:

1.

A1=4(1)-5= -1

A2=4(2)-5= 3

A3=4(3)-5= 7

2.

A1=2(1)= 2

A2=2(2)= 4

A3=2(3)= 6

3.

A1=3(1)+(1)^2= 4

A2=3(2)+(2)^2= 10

A3=3(3)+(3)^2= 18

4.

A1=1/3

A2=2/3

A3=3/3= 1

5.

A1=2(1)(1-2)= -2

A2=2(2)(2-2)= 0

A3=2(3)(3-2)= 6
