|
Answer» Nice ? Well, don\'t mind.... but may i know, from where you got this question ???Well, the answer will be :-The given series is 5+(-41)+9+(-39)+..+(-5)+81+(-3).This is consisting of two AP\'s.S1=5+9+13+....+77+81, where a=5, d=4S2=−41−39−37−...(−3), where a=−41 and d=2for S1, 81=5+(n−1)×4 ⇒ n−1 =764, hence n=20S20\xa0= 202×[5+81]=10×86 = 860 for S2, −3 = −41+(n−1)×2 ⇒ n−1 = 382,Hence,\xa0n=20S20\xa0= 202×[−41−3] = −10×44 = −440Total sum=S1+S2\xa0= 860−440 = 420Therefore, Answer = 420. |

The product of two consecutive positive integers is 306. We need to find the integers |
|
Answer» First consecutive positive no is x and another x+1 so product x(x+1)=360 So x square + x+1 whole square =306And factors are +18and -17So x= 17 x+1 = 17+1=18 We have to let the consecutive positive integers be x and x+1So x(x+1)=306 Let two consecutive positive integers =x,x+1Product of two consecutive integers=306X(x+1)=306X square+x-306=0By quadratic formula-b+-√d\\2a-1+-√1-4(1)(-306)/2-1+-√1225/2-1+-35/2X=-1+35/2=34/2=17Or x=-36/2=-18So x=17So two consecutive positive integers=17and17+1=18 |
