Question

The next term in the geometric sequence 1, 3, 9, 27, 81, ….. is

• A. 251
• B. 243
• C. 273
• D. 253

Answer 1

The correct option is B

243

In the given pattern 1, 3, 9, 27, 81, ….. consecutive terms are formed by multiplying the preceding term by 3.

1 $\times$ 3 = 3
3 $\times$ 3 = 9
9 $\times$ 3 = 27
27 $\times$ 3 = 81

So, the next term in the geometric sequence will be 81 $\times$ 3 = 243.
