Question

complete the series 15,30,60,105,165

Answer 1

yes i got it ...............

15 ,30 ,60,105,165

this series is continued by 15 table 

15

15+15 = 30

30 +30 = 60

60 +45 = 105

105 +60 = 165

165 + 75 = 240

240 + 90 = 330

330 + 105 = 435 

here 15 , 30 ,45, 60, 75 are the multiples of 15

In this way we should find

Answer 2

The next number is "240".

Step-by-step explanation:

The given series are:

15, 30, 60, 105, 165

To find, the next number = ?

The pattern follow:

+ 15, + 30, + 45, + 60, + 75, + 90, .....

30 = 15 + 15 = 30

60 = 30 + 30 = 60

105 = 60 + 45 = 105

165 = 105 + 60 = 165

Similarly,

? = 165 + 75 = 240

Hence, the next number is "240".
