Question

Find the first four terms of the sequence an = 5n-1.​

Answer 1

Answer:

let's see what to do buddy...

Step-by-step explanation:

" First four terms " means :

t(1) , t(2) , t(3) , t(4)

$t(1) = a(1) = 5(1) - 1 = 5 - 1 = 4 \\ t(2) = a(2) = 5(2) - 1 = 10 - 1 = 9 \\ t(3) = a(3) = 5(3) - 1 = 15 - 1 = 14 \\ t(4) = a(4) = 5(4) - 1 = 20 - 1 = 19 \\ \\ t(1) = 4 \\ t(2) = 9 \\ t(3) = 14 \\ t(4) = 19$

So the first four terms

are : 4 , 9 , 14 , 19
