Multiply the number with itself to obtain the next number in the sequence
The sum of the first n terms of a geometric sequence is : \\(\\frac{a(1-r^n)}{1-r}\\)
Multiply 3/5 to get the succeeding fraction.
Multiply numerator with smallest even number and denominator with second smallest odd number to obtain successive values.
Observe the sequence carefully.
a2/a1 = a3/a2, where an is the nth term.
Read the question carefully.
