(-23,-16) suppose(23,16) diffrent 7
(18,14) diffrent 45
(-52,-45) suppose(52,45) diffrent 7
(37,33) diffrent 4
(-65,-?) suppose(65,58) diffrent 7
so Ans Will be -58 - 7 years agoHelpfull: Yes(26) No(1)
- -23,-16,18,14,-52,-45,37,33,-65,
(-23,-16) difference is +7
(18,14) difference is -4
(-52,-45) difference is +7
(37,33) difference is -4
(-65,-?) difference is +7
so Ans Will be (-65+7)= -58 - 7 years agoHelpfull: Yes(7) No(0)
- Consider first -23 and -16 the difference between them is -7 and then next two terms 18 & 14 difference is 4.. similarly -65 and -62 is the answer
- 7 years agoHelpfull: Yes(2) No(1)
- here
-16 and -52 are divisible by 4. same -45 and -65 are divisible by 5. You can see the increment by the divisor. and there you see there 4*-4 , 4*-13, between which there are two terms. Same goes for 5*-9 and 5*-13. Here you can see the difference 9 and 4 ( pyramid series)and next should come 9 and 4 simmilarly. so we get -24 and -78 in the last term since there are two numbers between the negative numbers. - 7 years agoHelpfull: Yes(1) No(0)
- per two numbers: add +7.
ans = -58 - 6 years agoHelpfull: Yes(1) No(0)
- Sorry it's -58
- 7 years agoHelpfull: Yes(0) No(0)
- -58.
+7,-4,+7,-4,+7 - 7 years agoHelpfull: Yes(0) No(0)
- Split the series in two numbers
-23 + 7 = -16
18 - 4 = 4
-52 +7 = -45
37 - 4 = 33
-65 + 7 = -58
Answer is -58 - 7 years agoHelpfull: Yes(0) No(0)
- (6) >> 11,13,17,19,23,29,31,37,41,.........
all are prime number series
so next term is 43 - 7 years agoHelpfull: Yes(0) No(0)
- Take negative terms
(-23,-16) difference is 7
(-52,-45)=7
(-65,x) soo ans is -58 - 7 years agoHelpfull: Yes(0) No(0)
- without considering the signs the difference between first two numbers is 7
and the next two numbers difference is 4
continuing the same series so the answer is -58
-65+x=7
x=7-65=-58 - 5 years agoHelpfull: Yes(0) No(0)
