4,8,24,60 and 3,4,13 are two series
find diff first
4,16,36 (which are squares of 2,4,6)
1,9 ( squares of 1,3) so nxt in this series will be square of 5
i.e 25 ..... 13+25=38

SATYAWAN KUMAR  (10 years ago)

correct solution's are
there are two series 4,8,24 & 60 are the 1st series
and 3,4,13 are the second series.
first series obeys this rules....
4= 4+(1)^2
8= 4+(2)^2
24=8+(4)^2
60=24+(6)^2

second series (3,4,13) obeys this rules
4=3+(1)^2
13=4+(13)^2
so 13+(5)^2=38...is the correct answer...thank you..
