Question

an=7+(n-1)2 is the general rule for the nth term of the arithmetic sequence 7,9,11,13,15 ... true or false ?

Answer 1

True

Explanation:

The n th term rule for an arithmetic sequence is

`a_(n)` = a + (n - 1)d

where a is the first term and d the common difference

here d = 9 - 7 = 2 and a = 7, thus

`a_(n)` = 7 + 2(n - 1)
