Question

1+4+=5...2+5=12...3+6=21 5+ 8=

Answer 1

Answer:

the answer would be 34

Step-by-step explanation:

the way it goes is to add the sum of the answer before to the new product to get the next answer.

it would go:

1+4=5

5+2+5=12

12+3+6=21

21+5+8=34

Answer 2

The pattern is simply adding 3 to the first number to get the second number it is being added to. The first number is determined from simple adding.
Ex:1+3=4
2+3=5
3+3=6
Thus, the next ones in line will be:
5+8=13
6+9=15
7+10=17
Hope this helps!
