The sum of all the positive terms in the geometric sequence 54, - 36, 24, - 16, ... is

Annette [7]

Answer:

B. 97.2

Step-by-step explanation:

The sequence of positive terms is ...

54, 24, 10 2/3, 4 20/27, ...

This sequence has first term 54 and common ratio 24/54 = 4/9. The sum of the infinite series is ...

S = a1/(1 -r) = 54/(1 -4/9) = 54(9/5)

S = 97.2

The sum of the positive terms in the infinite series is 97.2.

Answer:

correct answer is : To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
