Answer:
let's see what to do buddy...
Step-by-step explanation:
" First four terms " means :
t(1) , t(2) , t(3) , t(4)
[tex]t(1) = a(1) = 5(1) - 1 = 5 - 1 = 4 \\ t(2) = a(2) = 5(2) - 1 = 10 - 1 = 9 \\ t(3) = a(3) = 5(3) - 1 = 15 - 1 = 14 \\ t(4) = a(4) = 5(4) - 1 = 20 - 1 = 19 \\ \\ t(1) = 4 \\ t(2) = 9 \\ t(3) = 14 \\ t(4) = 19[/tex]
So the first four terms
are : 4 , 9 , 14 , 19
