Question

what come next in series a 2 3 6 10 17 28

Answer 1

First, look for a pattern.

2 +1 = 3    3 +3 = 6    6 +4 = 10   10 +7 = 17    17 +11 = 28

Do you see a pattern?

Well it starts at +1, then +3, then the pattern starts

The next number is +4, or +1 and +3 added

The next is +7, or +4 and +3 added together

Continue and you will see the number you add is the same as the last two numbers you added added together.

So, the answer is 46
