Question

determine a recursion formula for the sequence 2,5,8,11,...3n-1

Answer 1

Answer:

an=a+(n-1)d is the formula

Answer 2

Answer:

Formula to find the $nth$ term $=a+(n-1)d$

Step-by-step explanation:

Since the given series is an Arithmetic progression as we can see that there is common difference between the terms.

$d=5-2=3\\d=8-5=3\\d=11-8=3$

We can see common difference is $3$

So a recursion formula for the sequence is $=a+(n-1)d$

Where $a= First term, \\d= common difference\\ , n= number of terms$
