Question

3, 15, 38, 78, 141, 235, 370, 552, ?​

Answer 1

Answer:

every n.o. has difference between 12 th table therefore ans is 648

Answer 2

Step-by-step explanation:

take difference 3-15=12

15-38=23

38-78=40

78-141=63

141-235=94

235-370=135

379-552=182

again find difference between two nos

12-23=11

23-40=17

40-63=23

63-94=31

94-135=41

135-182=47

see the similarities, they are prime nos

11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59

take alternative numbers, then we can see

11, 17, 23, 31, 41, 47, 59

exactly same as above

now add 59 to 182 then we get 241

241+ 552

answer is 793.
