Question

Find the term of an ap is 9,12,15,18 ........which is 39 more than its 36th term

Answer 1

hi friend,

given 9,12,15,18 ........ is in AP where a =9

d=3

then its 36th term is a+(n-1)d
→9+(35)3

→9+105

→114

given, the term which is 39 more than 36th term

→114+39

→153

now , an=a+(n-1)d

153=9+(n-1)3

144/3=n-1

48=n-1

n=49

so 49th term is 39 more than 36th term..


I hope this will help u :)

SupermanINFINITY : “nth term of an AP :

An = a + (n-1)d

36th term = 9 + (35)3 = 114

now , 114+39= 153

then ,
153 = 9+(n-1)3
n = 147/3 = 49 ."
