Answer 2

Answer:

21,25 : 4n + 1 : 105

Step-by-step explanation:

If You Will See The Numbers

It is an AP with common difference 4

So the nth Term Will be

a(n) = a + (n-1)*d

a = 5

d = 4

a(n) = 4n + 1

Now The Two Next Term is The 5th term and 6th Term

So, 4*5 + 1 = 21

4*6 + 1 = 25

Now 26th Term Will Be

4*26 + 1 = 104 + 1 = 105
