the 10th term from end of the a.p. -5, -10, -15,…, -1000 is
Solution:- -5, -10, -15,…, -1000
We can write this -1000, -995, -990............. -5
a=-1000
d=5
A10=a+(10-1)d
=-1000+9×5
=-1000+45
=-955 ans
The nth term of an A.P. is given by 7,12,17,22......is
Solution:-
Given ap is 7,12,17,22.......
a=7 , d=12-7=5
nth term of Ap is
an=a+(n-1)d
=7+(n-1)×5
=7+5n-5
=2+5n ans....
