Answer 1

Answer:

Explanation :

Answer 2

The value of missing number is equal to 396.

Step-by-step explanation:

The given sequence are:

13, 18, 28, 54, 104, 226, ?

To find, the next term = ?

The pattern follow,

Previous number + $(x^{2}+1)$,

Where, x is the consecutive prime number(x)= 2, 3, 5, 7, 11, 13

$18=13+(2^{2}+1)=13+5=18$

$28=18+(3^{2}+1)=18+10=28$

$54=28+(5^{2}+1)=28+26=54$

$104=54+(7^{2}+1)=54+50=104$

$226=104+(11^{2}+1)=104+122=226$

Similarly,

$?=226+(13^{2}+1)=226+170=396$

The value of missing number = 396

Hence, the value of missing number is equal to 396.
