Question

Find the next term in the series : 80, 40, 40, 60, 120, 300, 900, ?​

Answer 1

Answer:

320

Step-by-step explanation:

You all know the game take a number in mind then divide by 2 multiply by 2 and add by 2 divide by 2 which no. we taken add that so I got this

80÷2=40×1=40+20=60×5=300+20=320

Answer 2

Given:

We have given as series which is  80, 40, 40, 60, 120, 300, 900.

To Find:

We have to find out the next term of the given series?

Step by Step Explanation:

• We have the given series is  80, 40, 40, 60, 120, 300, 900

• First of all we will try to find out the any particular pattern in the given series becuase there is always particular type of pattern in the series.

• By observing the series we get that second term of the series is half the first term

• Third term of the series is 1 times the second term

• Fourth term of the series is 3 by 2 times the thord term

• Fifth term of the given series if 2 times then the fourth term

• Sixth term of the series is 5 by 2 times then the fifth term
• Seventh term of the series id 3 times the sixth term
• Hence the pattern is given by the formula with term like in the way

       $\bf80\times\frac{1}{2} =40\\40\times1=40\\40\times\frac{3}{2} =60\\60\times2=120\\120\times\frac{5}{2} =300\\300\times3=900$

• Hence the term will be given by

        $900\times\frac{7}{2} =3150$

Hence, the next term will be 3150.
