(3) if the first term of a G.P is 5 andcommon ratio is -5 then which termis 3125 ?o56O78 About the author Natalia

Answer: 5 is correct answer for this question Step-by-step explanation: a=5 and r=-5 for gp an=arn-¹ a.t.q =5×-5^n-1=3125 -5^n-1=3125/5 -5^n-1=625 -5^n/5=625 -5^n=5⁴×5 -5^n=5⁵ so bases are same so exponent are same so n=5 ans Reply

Answer:5 is correct answer for this question

Step-by-step explanation:a=5 and r=-5

for gp

an=arn-¹

a.t.q

=5×-5^n-1=3125

-5^n-1=3125/5

-5^n-1=625

-5^n/5=625

-5^n=5⁴×5

-5^n=5⁵

so

bases are same so

exponent are same

so n=5 ans
