Alternate series of odd numbers with change of signs
4-11=7==-7
-5+14=9
11-22=-11==11
-14-13===-27Likhitha

4+(-5)=-1
11+(-14)=-3
so it iis having a sequence of odd numbers.In the next sequence we should have"-5" because after the sequence of odd -1 & -3 we have -5.
to get it 22+x=-5
x=-27

As from a to b==4 ,b to c==3 so a to c==sqrt(4+3)==5RAJALAKSHMI

F proportional to T ^2 so, f=kT^2 (where T is const.) 64=k2^2 k=64/4=16 then in 6sec falling distance (fd)=16*6^2 16*36=576cm(ans.)

Answer is 1.5 ftLet us assume one tree grows xft in 4 yrs, 2nd tree grows 3/5(x)ft...Total x+3/5(x)=8x=5 ft..hence 1st tree 5ft 2nd tree 3 ft for 4 yrs2nd tree for 2 yrs is 3/2=1.5 ft

The answer is1) If it is a row based then 1258+2(9(5-1)+(8-1))=1258+2(36+7)=1258+86=13442)
If it is column based then1258+2((7(8-1)+(5-1))=1258+2(49+4)=1258+106=1364.
