Question

Find the nth term of this number sequence. 1,7,13,19...

Answer 1

Answer:

Step-by-step explanation:

a=1

c.d. d=13-7=6

$a_{n} =a_{1}+(n-1)d\\a_{n}=1+(n-1)6\\a_{n}=1+6n-6\\a_{n}=6n-5$

Answer 2

Answer:

This sequence is arithmetic, and the next term is 25

Step-by-step explanation:

The common difference of the sequence is 6, so the next term is 19+6=25.

The difference between the consecutive terms is constant => sequence is arithmetic.

7-1=6

13-7=6

19-13=6
