Question

if five times the 5th term of an AP is equal to Eigth term
Show that it's 13th term is zero​

Answer 1

Step-by-step explanation:

Given 5 times 5

th

term 8 times 8

th

term

5(a+(5−1)d)=8(a+(8−1)d) ......... [ t

n

=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=13

th

term.

Hence, 13

th

term is zero.
