1, 8, 25, 52, 89, 136, next number would be

Dr.Dipin Singh   13 years AGO

series is .....n^2 + (2n-2)^2

1, 8, 25, 52, 89, 136, next number would be 193.
1=1^2+(2-2)^0=1+0=1
8=2^2+(4-2)^2= 2^2+2^2=4+4=8
25 = 3^2+4^2
52= 4^2 +6^2
...
136 = 6^2+10^2
7^2+12^2= 49+144=193.... option 1

x^2 + square of next even no
as
1^2+0^2= 1
2^2+2^2=8
similarly
136 = 6^2+10^2
7^2+12^2 =49+144=193

Leena   13 years AGO

using series, n^2-4*(n-1)^2,
next number in 1, 8, 25, 52, 89, 136 series would be 7^2 +4*(6^2) =49+4*36 =49+144 =193
