Question

13,34,74,?,290 what is the number of ? ​

Answer 1

The missing term is 170

Solution:

13, 34 , 74 , ? , 290

We have to find the missing term in series

Let us analyse the logic used here

$First\ term = 2^2 + 3^2 = 4 + 9 = 13\\\\Second\ term = 3^2 + 5^2 = 9 + 25 = 34$

$Third\ term = 5^2 + 7^2 = 25 + 49 = 74$

The numbers are addition of two consecutive prime number's square

Therefore,

$Fourth\ term = 7^2 + 11^2 = 49 + 121 = 170$

$Fifth\ term = 11^2 + 13^2 = 121 + 169 = 290$

Therefore, complete series is:

13, 34 , 74 , 170 , 290

Thus the missing term is 170
