1,3,9,27,81 find the next two terms

243, 729

Step-by-step explanation:

The pattern of the set of data is multiplying each number by three to get the next number. So the next 2 numbers would be:

81*3=243

243*3=729

Hope this helps!

1. If it is intersection then it SHOULD be included in both the sets right? Now we know that odd numbers from 1-100 but the second set are multiples of 5 from 50-150! So we mainly need to look for common numbers which are ODD and are a MULTIPLE OF 5 BETWEEN 50 - 100!! So A={51,53,57,59,6199} B={55,60,65,7095} [We stop till 100 because set A has no such element] So what is A ∩ B here? A ∩ B = {All odd numbers and multiples of 5 between 50 - 100}
