In the chapter arithmetic progressions of exercise 5.1. How i solve the question in easy way. Because it is very tough for me . In class 10th it is very important for board exams Write first four terms of the A.P. when the first term a and the common difference are given as follows: (i) a = 10, d = 10

aÂ = 10,ÂdÂ = 10Let us consider, the Arithmetic Progression series beÂ

a_{1},Â a_{2},Â a_{3},Â a_{4},Â a_{5}Â â€¦a_{1}Â =ÂaÂ = 10a_{2}Â =Âa_{1}+dÂ = 10+10 = 20a_{3}Â =Âa_{2}+dÂ = 20+10 = 30a_{4}Â =Âa_{3}+dÂ = 30+10 = 40a_{5}Â =Âa_{4}+dÂ = 40+10 = 50And so onâ€¦

Therefore, the A.P. series will be 10, 20, 30, 40, 50 â€¦

And First four terms of this A.P. will be 10, 20, 30, and 40.
