Question

sum of infinite series 1 + 1 by 3 + 1 by 3 square + infinity is​

Answer 1

Step-by-step explanation:

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.

Answer 2

Step-by-step explanation:

As written (with 3n as the final term), the sum is infinity.

A more typical problem about the sum of a decreasing (converging) geometric series would be this:

1+131+132+133+⋯+13n

The formula for the sum of a converging geometric series is:

Sn=a1(1−rn)1−r, where a1is the first term and r is the common ratio.

Use this formula with a1=1 and r=13 :

Sn=1(1−(13)n)1−13=123=32
