Answer:
5+6+8+12+20
let us see difference between 5 and 6
= 1
let us see difference between 6 and 8
= 2
Let us see difference between 8 and 12
= 4
let us see difference between 12 and 20
=8
let us now see the patterns
the patterns shows that every number is twice the number before
And now if we have to find another number then it would be
20+16= 36
36+ 24 = 60
maybe u know now the answer
the pattern is n × n
