Read Solution (Total 10)
-
- take 2 different series
1)1,4,10,19,?
and 2) 3,5,9,15
so in 1st series 1,1+3,1+3+6,1+3+6+9,1+3+6+9+12=31
ans=31 - 8 years agoHelpfull: Yes(15) No(0)
- 1 st digit+3= 3rd digit
3rd digit+6=5th digit
5th digit+9=7th digit
7th digit+12=9th digit(31 ans)

- 31
1,3,4,5,10,9,19,15,31
1-3=1+3=4
4-10=4+6=10
10-19=10+9=19
19-31=19+12=31

- 31
take 1,4,10,19 one set t difference is 3,6,9,so next 12
add 19+12 we get 31 ans - 8 years agoHelpfull: Yes(1) No(0)
- 1,3,4,5,10,9,19,15 ...odd position difference is multiple of 3 so answer is 31

- 31
1+3=4
4+(3*2)=10
10+(3*3)=19
19+(3*4)=31

- Take two series
1)1,4,10,19,? { [1-4=3,4-10=6,10-19=9] So,differeneces are 3,6,9 the next number will be 12. So, add 12+19=31 }
