Answer is 79...
Solution
The next number is formed by adding the previous number with the individual digit in the number...
eg:-
25=17+1+7
32=25+2+5
37=32+3+2 and so on
Final value is 71+1+7=79

hi
i got 97 since
result
25-17=8
32-25 =7 result is decreased by 1 compared to previous result
37-32=5 result is decreased by 2 compared to prev result
47-37=10 result is doubled compared to prev result
58-47=11 result is increased by1 compared to previous result
71-58 =13 result is increased by 2 compared to previous result
now the previous result should b doubled!
i.e 13*2=26
therefore 71+26=97
thats what i thought!
