Calculate the partial sum s for the sequence 243,81,

363

Step-by-step explanation:

We have to find partial sum for the sequence 243 , 81 , 27 up to 5 terms(S5 given)

The sequence actually is 3^5,3^4.,3^3

Therefore first 5 terms are 1) 3^5 I.e. 243

2) 3^4 I.e. 81

3) 3^3 I.e. 27

4)) 3^2 I.e. 9

5) 3^1 I.e. 3

Adding all those no. we get partial sum of first 5 no. of the sequence

So, 243 + 81 + 27 + 9 + 3

= 363

Hope it helps!!!

D. 363 is the one

the answer is ! ?

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
