Question

Can anyone help me with this question?????????????????????????????????????????????????????

A math club had 7 members in its first year. It had 22 members in its fourth year and 32 members in its sixth year. Assuming a constant rate of increase, how many members will the math club have in its thirteenth year?

Answer 1

First year club had 7 members
Fourth year they have 22
Sixth year they have 32
so from first to fourth or in 3 years its members increase by (22-7)=15
from fourth to sixth or in 2 years its members increases by (32-22)=10
so in 3 years it increase by 15
\[or\ in\ a\ year\ members\ increase\ by\ 5 \]
So in its thirteenth year
no of years from first to thirteenth =(13-1)=12 years
in 12 years members will increase by 12*5=60
In first year it has 7 members so in thirteenth year it will have=60+7=67 members
