Question

Find the missing term in the following number series.
3,7, 19, 39, ?, 103
0 49
O 51
O 53
O 67​

Answer 1

Answer:

Surely 67

Step-by-step explanation:

Because

3+4=7

7+12=19

19+20=39

39+28=67

67+36=103

See first we added with (4x1)=4

Then with (4x3)=12

Then (4x5)=20

Then(4x7)=28

Then (4x9)=26

You can see that we are multiplying 4with odd numbers and then adding their products
