Question

Write down the GP, whose fifth term is 80 and tenth term is 2560

Answer 1

Answer:

AP is -1904, -1408, -912....

Step-by-step explanation:

I think you mean AP

so fifth term= 80

a+4d= 80----------1⃣

tenth term= 2560

a+9d = 2560------2⃣

subtracting 1⃣ and 2⃣(by elimination method)

you will get d= 496 and a= -1904

so AP is -1904 ,-1408, -912......and so on.
