Question

What is the 5th term from the end of the AP 2,7,12,....,47 ?

Answer 1

Answer :-

a = 47 , d = 7 - 2 =5 , n =5

we know that,

an = a - (n -1)d

an = 47 - (5 -1)5

an = 47 - 4 × 5

an = 47 - 20

an = 27

so the 5th term from last of given ap will be 27.

if satisfied then mark it as brainliest.
