Answer:

If given 5 times the fifth term of an A.P. is equal to 8 times its eight term, show that its 13th term is zero.

Step-by-step explanation:

ANSWER

Given 5 times 5th term 8 times 8th term

5(a+(5−1)d)=8(a+(8−1)d) ......... [ tn=a+(n−1)d ]

5a+20d=8a+56d

⇒3a+36d=0

∴a+12d=0

Comparing this with a+(n−1)d,

we get ,n−1=12

n=13th term.

Hence, 13th term is zero.

HOPE IT'S HELPFUL......
