Explode: If there was 6th term which you have to find then you have to say n = 11

shubhamdixit2002: mai yeh kehna chahta hu ki hame jo bhi term nikalna hai toh hum uska n Kaise find karengey

Explode: I send you message bro

kvnmurty: Good

Explode: Brainliest please .

Explode: if possible

kvnmurty: in some question one easy short cut was found like that.. for finding 13th term say n=25...like that.

kvnmurty: Because in the ratio on LHS we have 2a+(n-1)d. Divide by 2 in the numerator & denominator. . u get a+(n-1)/2 ×d.... so for getting ratio of 5th terms., (n-1)÷2 = 4. So n=9.

kvnmurty: Understand @ shubham dixit?
