4+5=9(squre of 3)
5+11=16(4)
11+14=25(5)
14+22=36(6)
22+27=49(7)
Dear JKPAWAR Read the question carefully first. and than give ur ans.
and can u please explain this.. so that other can understand that wht u want to say
Negate the alternate number:
4 + 1 = -5 (negate) (Take the absolute of -5 and use in next step)
5 + 2 = 7 + first (4) = 11
11 + 3 = -14 (negate)
14 + 4 = 18 + first no (4) = 22
22 + 5 = -27 (negate)
27 + 6 = 33 + first no (4) = 37
37 + 7 = -44 (negate)
44 + 8 = 52 + First no (4) = 56
56 + 9 = -65 (negate)
65 + 10 = 75 + First No (4) = 79
....so on and so forth
so the series is
4,-5,11,-14,22,-27,37,-44,56,-65,79...............
