Step-by-step explanation:
Logic- Two different patterns are being followed here alternatively. A combination of multiplication and addition is taking place.
1. Firstly, the numbers are multiplied by a given number- 7,34,.....
So, here first number gets multiplied by 2 ( 17*2=34) to get the second number
2. Next, addition is performed and 4 gets added to the second number, 34 to get the third number- 17,34,38,...
3. Again the first logic of pattern is applied, i.e. multiplication takes place- third number gets multiplied by 3( this number gets incremented by 1 every time)
17,34,38,114,....
4. Again the second logic or pattern is applied, i.e. addition takes place- 6 is added to the fourth number
17,34,38,114,120
In short;
17×2=34
34+4=38
38×3=114
114+6=120
120×4=480
so as u can see that the no. from which we r multiplying then we are just adding the double of it so in480 we will add double of 4 that is 8
so,480+8=488
The missing number is 488 and the series is 17,34,38,114,120,480,488.
