1.

4,2,2,3,6,15,45 If (2700)^(P) is the term of the sequence where P is the P^(th) term of sequence then find 'P'.

Answer»

8th
9th
10th
11th

Solution :PATTERN of the series is

So, next terms will be `45xx3.5, 45xx3.5xx4, 45xx3.5xx4, 4.5`
Do not CALCULATE exact VALUES. Just calculate APPROXIMATE values because with increase in values next term will be far away from 2700
So, `45xx3.5` is approx. 150
And, `150xx4` is approx. - 600
`600xx4.5` is approx. `xx2700`
So, multiples of 4.5 is nth term which is 10th term.
