geometric series

I am sorry but your question doesn't make sense to me.
Could it be a problem with your translator?

they meant that in 1984 14% of adults had no close friends. They say that the average amount of aults that have close friends that increased is 0.72% but the increase was 23.7%. Now they are asking you to put together a math term that shows that 14% of adults had no close friends. Melody that is what the person meant

Ok, thanks maths lover but it still doesn't make sense. I'll put my problems with the question in red.

in 1984 near ly 14% of all adults has no close friends.
On average the increase is 0.72% per year?
in 2006 it was 23.7 %

If it increased by 0.72% per year it would not be 23.7% in 2006. It would be 16.4%

write and equations nth term that gives the equation that has no close friends in 1983
