What is the nth term of 10 17 24 31 38?
The differnace between the numbr is 7, therefore the first part
of the formula will be 7n, now for the first term we replace n with
one so nx7=7 and to get to 10 you need to add 3 making the nth term
7n+3,
To check your answer you must replace n with the two (for the
second term) which comes to 14 to get to seventeen you need to add
three so the formula nth term 7n+3,
hope this helped
