Question

What is the third term of this multiplication pattern? multiplication pattern using the formula 3 • 7n – 1 A. 147 B. 21 C. 1 D. 441

Answer 1

The way you wrote it, it should be 60.
But the way I think you meant to write it was $(3)(7 ^{n-1} )$
Which in this case, 3-1=2 so (3)($7 ^{2}$)=147
