Question

What is the recursive formula for this sequence 12,16,20,24,28

Answer 1

ANSWER

The recursive formula is

$a_n = a_ {n - 1}+ 4$

EXPLANATION

The given sequence is 12,16,20,24,28

The first term of this sequence is

$a_1=12$

The common difference is

d=16-12

d=4

The recursive formula is given by

$a_n = a_ {n - 1}+ d$

So we need to substitute the known values to get

$a_n = a_ {n - 1}+ 4$

Answer 2

I think it’s 12 table I believe
