## anonymous 3 years ago What is the seventh term of a sequence whose first term is 1 and whose common ratio is 3? please someone help me

1. ParthKohli

$a_n = a_1 \times r^{n-1}$

2. anonymous

3. ParthKohli

The seventh term is the product of the first term and the common ratio multiplied itself $$7-1=6$$ times

4. ParthKohli

Does that help?
