Question

Follow the rules to create two number sequences that go to the fifth term each.

Rule 1: Multiply by 3 starting from 10. Rule 2: Subtract 7 starting from 58. What is the first term that appears in both sequences?

Answer 1

30

Explanation:

10x3=30

30x3=90

90x3=270

270x3=810

58-7=51

51-7=44

44-7=37

37-7=30

also 90,270,and 810 are above 58 so the answers has to be 30

that is just the method to calculate those types of problems
