Answer 1

Given: During the first year they will  plant 100 trees. Each succeeding year, they will plant 50 more trees than they  planted the year before.

We have to find,

1. How many trees will they plant during the fifth year?

2. How many trees will they have planted by the end of the tenth year?

Here, We know that in the first year they planted 100 trees.

So, in the second year, they planted $100+50=150$

in the third year, they planted $150+50=200$

in the four years, they planted $200+50=250$

in the five-years, they planted $250+50=300$

in the six years, they planted $300+50=350$

in the seven years, they planted $350+50=400$

in the eight years, they planted $400+50=450$

in the nine years, they planted $450+50=500$

in the ten years, they planted $500+50=550$

So, 1. in the fifth year they planted 300 trees.

2. at the end of the tenth year they planted 550 trees.
