Solution 1 is incorrect because it has (15 * 15) = 225. Here 15 does not belong to the prime number. Hence solution 2 is correct.

195+60=255,
255+30=285,
285+60=345,
345+30=375
so this answer is 375

Ponnganti Sreenivasa 9 years ago

165 195 255 285 345
+30. +60. +30. +60 and +30+345=375
But. +30. +30. +30So 345+60+30=43
So answers C &D

Himanshi Chaturvedi 10 years ago

In the solution 2, the last line is written wrong. Instead of adding 30, 90 must be added to obtain the answer as 435.
The answer 375 is wrong.

Rehana Shaik 10 years ago

Successive addition of 30 and 60 also makes a resonable result. 375 also must be answer

Om Shiv 10 years ago

there should be another answer for this and it is 375
solution:
195-165=30
255-195=60
285-255=30
345-285=60
so the next no. must be 345+30=375
