Answer 2

Given:

We have given the series with terms 4,5,8,15.

To Find:

We need to to find the next term of the given series?

Step-by-step explanation:

       Series:

• In any of the series any  particular format is  being follwed  used bythe different terms.

• The format for the follow different terms of the series will always same.

• Now we have given the series with terms  4,5,8,15.?

• First of all we will always  try to find to establish and try to form particular format is followed here by the given series

• By observing the given terms and focusing on them we get second term is 2 times of first term minus 3 and third term is two times of second term minus 2 and the fourth term is two times of third term minus 1.

        Hence we get the pattern which is written as

        $4\times2-3=5\\5\times2-2=8\\8\times2-1=15\\15\times2-0=30$

Hence , we get that the next term will be 30.
