Question

Find the fifth term from the end of A.P -19 -14 -9 .....51

Answer 1

Step-by-step explanation:

since,a100=a+(n-1)d

a100=10+(99)5

a100=450

now there are 100 terms totally now formula is

(n - r + 1) {th}^{term}(n−r+1)th

term

r=50 now,you get 51th term i.e.50th term form last is 51th term form starting

so a51=10+(50)5

a51=260

so 50th term from last is 260
