Question

PLEASE HELP. TEST TOMORROW.

Look at the recursive formula.
A1=6
for n>1,An=A(n-1)+4

What are the first 4 terms of this sequence?
A. 5,6,7,8
B. 6,10,14,18
C. 9,12,15,18
D. 10,14,18,22

how do i solve this??

Answer 1

you have \(a_1=6\) right? so next step is to compute \(a_2\)

Answer 2

\[a_2=a_1+4=6+4=10\] for the next term

Answer 3

one after that is
\[a_3=a_2+4=10+4=14\] etc etc

Answer 4

is that all i have to do?

Answer 5

yes

Answer 6

thank you
