Question

Rosa made 1 phone call on Thursday, 3 phone calls on Friday, 9 phone calls on Saturday, and 27 phone calls on Sunday. If this pattern continues, how many phone calls will Rosa make on Monday?

Answer 1

The answer is 81

This is because each number is multiplying by three as time goes on.

1×3=3. 3×3=9 9×3=27 and 27×3=81

Therefore, the answer to this question is 81 phone calls

Answer 2

73 because it’s obviously 73 because 73 +73 -73 is 73
