Question

choose the next term of the Series 15, 17, 20, 25, 33, 46, 67​

Answer 1

Answer:

Next number is 101

Step-by-step explanation:

Given series and Difference between successive term are given below one by one

15           17           20           25           33           46           67           ....        

      2             3              5             8             13            21          

                         (5=2+3)   (8=5+3)   (13=8+5)  (21=13+8)  now next No.(21+13=34)          

Now again taking original series

15           17           20           25           33           46           67           ....  

       2             3              5             8             13            21         34

Now taking sum of diagonal element from top left to bottom right in above two series give next right element in top series.

15 +2 =17

17+3  =20

20+ 5=25

25+8 =33

33+13=46

46+21=67

67+34=101
