Question

8, 15 ,22, 29 ...

A) What is the 9th term of the sequence?

B) is 2345 a term in the sequence? Give a reason

Answer 1

Explanation:

It is an arithmetic sequence with ratio=7

the 9 th term is 8+8*7=8+56=64

2345=8+n*7

n*7=2345-8=2337

n=2337/7=333,8....

it is not a term cause n should be a natural number ( 333 for example)
