Question



What is the next number of the following sequence?
3,6,13,26,33,66,...

​

Answer 1

Answer:

73

Step-by-step explanation:

3x2=6

6+7=13

13x2=26

26+7=33

33x2=66

we see that the pattern is alternating between 'x2' and '+7' and also the last we did x2 so now we have to do +7

so,66+7=73

pls mark me as the brainliest :)
