- 1370,1320,1070,-180,?
1370-50*(5^0)=1320
1320-50*(5^1)=1070
1070-50*(5^2)=-180
-180-50*(5^3)=-6430.
So, the next number in the series is 6430............ - 9 years agoHelpfull: Yes(82) No(10)
- 1370-1320=50 -->50*5=250
1320-250=1070-->250*5=1250
1070-1250=-180-->1250*5=6250
-180-6250=-6430......so ans:-6480

- 1370 - 50 = 1320 (50 * 5 = 250 )
1320 - 250 = 1070 (250 * 5 = 1250 )
1070 - 1250 = -180 (1250 * 5 = 6250)

- since from 1st no 50 is substracted and then the 5x50=250 is subsracted then 5x250=1250 is substracted
and then 5x1250=6250 is substracted from -180
so the ans is -6430 - 9 years agoHelpfull: Yes(3) No(0)
- 1370-(10*(5^1))=1320
1320-(10*(5^2))=1070
1070-(10*(5^3))=-180
-180-(10*(5^4))=-6430

- -6070 is rit
- 9 years agoHelpfull: Yes(1) No(10)
- 1320-1370 = -50
1070-1320 = -250 = 5(-50)
-180-1070 = -1250 = 5(-250)
x+180 = 5(-1250) = -6250
x = 6430 - 9 years agoHelpfull: Yes(1) No(1)

- 1370 to 1320 difference is 50
1320 to 1070 difference is 250
1070 to -180 difference is 1250
-180 next no will be -6250 because to multiply the diffrence in 5 - 9 years agoHelpfull: Yes(0) No(1)
- Let 1370,1320,1070,-180,x
1320-1370=-50
1070-1320=-250 (-50*5)
-180-1070=-1250 (-250*5)
Similarly -1250*5=-6250
Hence x-(-180)=-6250
x=-6250-180
Therefore x=6070 - 8 years agoHelpfull: Yes(0) No(0)
