Explanation
Explanation
Step 1: Look for a pattern
Check how each number is obtained from the previous one.
- 1×2+2=4
- 4×2+2=10
- 10×2+2=22
22×2+2=46
The rule is:
Multiply by 2 and then add 2.
Now apply the same rule to the last given number:
46×2+2=92+2=94
PRO TIP
Re-check your working by substituting the answer back into the original question.
