There are ‘a’ trees in the village Lat. If the number of trees increases every year by ‘b’, then how many trees will there be after ‘x’ years?

उत्तर
Initial number of trees in the village = a
Increase in the number of trees every year = b
∴ Number of trees in the village after x years = Initial number of trees in the village + Increase in the number of trees every year × `x`
= a + bx
Thus, the number of trees after x years is a + bx.
