Can anyone help

Answer 9

ok... so the 1st term is 3 and it increases by 3...

so the general term is

\[a_{n} = 3 + (n - 1)\times 3\]

just simplify it

Answer 10

Is it f(n) = 3n + 3; n>= 1
Or f(n) = 3n - 3; n>= 1
Or nethier

Answer 11

Answer 12

well what happens with

f(n) = 3 +(n - 1) 3

f(n) = 3+ 3n - 3

you need to simplify this...

Answer 13

Ohhhhhhh i get it 6n -3 n is equal to oupr greater than 1
