Question

Write down in terms of n, an expression for the nth term for the nth term of the following sequences 1 8 15 22 29

Answer 1

Answer:

It's observed that every term = previous term +7

and 1st term is 1

so the expression will be

value of the nth term = 1+7(n-1)

Answer 2

Answer:

7n-6

Step-by-step explanation:

the difference between the numbers is 7 so from 1-8 is 7 8-15 is 7 so on

so add the n

next part normally you would minus the 7 from the first number but it is one so  just to it the opposite way round 7-1 which is 6 and to know if it is 7n-6 or 7n+6 ask yourself is the 6 bigger than 7 if so 7n+6 if not (smaller in this case) 7n-6
