Question

Find the 10th term from the end of the A.P. 4,9,14....................254.
Please jaldi Bata do pls

Answer 1

u can see that first term 'a' from last = 254

difference between consecutive terms is =- 5

so using formula.....

t(10) = 254+(10-1) d
= 254-45
= 209

hence tenth term will be 50
