Answer 1

Answer:

a)n+6

b)n×3

c)?

Step-by-step explanation:

a)4+6=10

10+6=16

16+6=22..........

b)5×3=15

15×3=45

45×3=135.....…......

c)????????

Answer 2

Answer:

$(a) \: 6n-2\\(b)\: 5 \times 3^{n-1}\\(c)\: 5({-1^n}+3)$

Step-by-step explanation:

$6(1)-2=4$

$6(2)-2=10$

$5 \times 3^{(3)-1}=45$

$5 \times 3^{(4)-1}=135$

$5(-1^{(5)}+3)=10$

$5(-1^{(6)}+3)=20$
