METHOD 1
------------------

1+5 = 6 × 2 = 12

2+10 = 12 × 2 = 24

3+15 = 18 ×2 = 36

5+25 = 30 × 2 = 60

NOTE :- all we have to do is add the given no. and multiply it by 2.

METHOD 2
-------------------

5 × 2 = 10 + 2 = 12

10 × 2 = 20 + 4 =24

15 × 2 = 30 + 6 = 36

20 × 2 = 40 + 8 = 48

25 × 2 = 50 + 10 = 60

NOTE :- all we have to do is multiply the number of middle row by 2 and add even no. with it.

Answer 2

hey there !!

$\red{METHOD\: FIRST}$

just duble both sides such as ....

1×2+5×2=12
2×2+10×2=24
3×2+15×2=36
4×2+20×2=48

so the next term will be same like above...

5×2+25×2= $\boxed{60}$

and ur answer is 60....

$\red{METHOD\: SECOND}$

just add both numbers and then make double means....

(1+5)×2=12
(2+10)×2=24
(3+15)×2=36
(4+20)×2=48

so next term is ..
(5+25)×2=60

again 60 is ur answer...

hope u liked...☺️
