13, 50, ?, 244, 425, 679, 1015
Answers
Question :- complete the given series :-13,50,?, 244,425,678,1015 .
Solution :
we use difference method to solve this problem. Because numbers are not near to any multiple, or square .
From image , we can see that,
→ 50 - 13 = 37
Now,
Lets start from back .
→ 1015 - 678 = 337
→ 678 - 425 = 253
→ 425 - 244 = 181
if we will solve these 3 numbers correctly , all over problem will be solved .
Again finding difference now,
→ 337 - 253 = 84
→ 253 - 181 = 72
As we can see , here we see our pattern.
→ 84 - 72 = 12 .
Now, we will start from down .
→ 72 - 12 = 60
Subtract this from 181, we gets previous ,
→ 181 - 60 = 121
finally subtracting his 121 from 244 we get,
→ 244 -121 = 123 = ? . (Ans.)
[ From image you can see all down parts also..]
