Question

Verify whether the following sequence is G.P. If so, write tn: 

3, 4, 5, 6, ...

Sum

Solution

3, 4, 5, 6, ...
t1 = 3, t2 = 4, t3 = 5, t4 = 6, ...

Here, `"t"_2/"t"_1 = 4/3, "t"_3/"t"_2 = 5/4, "t"_4/"t"_3 = 6/5`

Since, `"t"_2/"t"_1 ≠ "t"_3/"t"_2 ≠ "t"_4/"t"_3`

∴ the given sequence is not a geometric progression.
