Answer 1

Answer:

40

Step-by-step explanation:

10,13,16,19.....has increase 3 every time and

5,10,20,?....starting from 5,get multiplied by 2 every time

5*2=10

10*2=20

20*2=40

so ans is 40

Answer 2

Answer:

We will get the series is10,5,13,10,16,20,19,40 ….

Step-by-step explanation:

• As per the question we have to evaluate the given data.

         Given data:- 10,5,13,10,16,20,19.

         To find:- Complete the series 10,5,13,10,16,20,19.

        Solution:-

• This series has two types of sequence and two types of methods. This number series question.

• The first sequence is 10,13,16,19.

• And the method is:

        Add 3 in each number like

• First is 10 now add 3 equal to13 which is the third number now next add 3 in 13 equal to 16.

       And next doing similarly

       $10+3=13\\13+3=16\\16+3=19$

      as similarly,

• And the second sequence is 5,10,20
• Method: in this sequence, we add numbers with the same number.
• The first number is 5 now add 5 as the same number then equal to 10 now add 10 in 10 which is also the same number then equal to 20 and apply this method next number

        $5 + 5 = 1010 + 10 = 2020 + 20 = 4040 + 40 =80$

       as similarly,

• And add these both sequences in altrenetive we get,

      So series is 10 , 5 , 13 ,10 , 16 ,20 ,19 ,40 ….
