Number-Series

Answer :

16 x 0.5 + 0.5 = 4.5

8.5x 1+ 1 = 9.5

9.5x 2 + 2 = 21

21 x 4 + 4 = 84

84 8 + 8 = 712

Answer :

28 + 2² = 28 + 4 = 32

32 - 3² = 32 - 9 = 23

23 + 4² = 23 + 16 = 39

39 - 5² = 39 - 25 = 14

14 + 6² = 14 + 36 = 50

50 - 7² = 50 - 49 = 1

Answer :

4

9 = 4x2+1

17 = 9x2-1

35 = 17x2+1

69 = 35x2-1

139 = 69x2+1

277 139x2-1

Answer :

5

5 x 1+1² =5+1=6

6 x 2 + 2² = 12 + 4 = 16

16 x 3 + 3² = 48 + 9 = 57

57 x 4 + 4² = 228 + 16= 244

2445 + 5² = 1245

Answer :

1+1²+1³=3

2+2²+2³=14

3+3²+3³= 39

4+ 4²+ 4³ = 84

5+5²+ 5³= 155

6+6²+6³= 258
