Question

show that 10,11,12 cannot be term of a g .p.

Answer 1

hello Frnd

A sequence is GP when it's there is a common ration between them.

GP stands for Geometric progression.

To show 10,11,12 cannot be in GP, we have to assume it is a GP

And if it's a GP, there must be common ratio

a2/ a1 = a3/a2

11 / 10 = 12 /11

Since a2 /a1 is not equal to a3/ a2

There fore it is not a GP , hence proved



hope it helps
