The sum of the sequence 1+3+9+27+....~​

Answer»

Step-by-step explanation:

the sum of the SEQUENCE is 243 .

because if we MULTIPLE 1*3 we get 3.

so in the sequence we write three.

then if we multiple 3*9 we get 27 so we write 27 in sequence. so if we multiple 27 *9 we get 243 .

so 243 is next sum of sequence .

thank you for this nice question
