How to solve number sequences
- Look at how much each number changes from the one before it.
- If the change is always the same, keep adding it. If the changes grow, look for a pattern in the changes themselves.
- Choose the next number from four options, then press Next.
Rules include adding or subtracting a fixed amount, multiplying, two alternating steps, steps that grow, square numbers, and adding the two previous numbers.
The wrong choices are close to the right one, so estimating by size is not enough. Check the rule against all five numbers.
