Question

A arithmetic sequence start as 5,9,13, what is the next? Is 2012 a term of the sequence?why?

Answer 1

Step-by-step explanation:

The next term of the sequence will be 17

Since the first term is 5 and the common difference is 4

So you would get the fourth term by the formula -

a+3d

Using the formula

Sn=n/2[2a+(n-1)d]

Sn = 2012

n= This is the value you will get after solving , if it is a natual number , then you must understand that 2012 is a term of the sequence else not .

a= 5

d=4
