# Find the sum.(a) 1 3 + 2 3 2 + 2 2 3 3 + 2 3 3 4 + ... + 2 9 3 10 (b) 1 + 1 2 1 / 2 + 1 2 + 1 2 3 / 2 + ...

To determine

(a)

To find:

The sum of 13+232+2233+2334+...+29310.

Explanation

Given:

The expression 13+232+2233+2334+...+29310.

Approach:

Use formula for sum of finite geometric sequence which is Sn=a(1rn1r)

Calculation:

The elements of the given sum as in geometric series.

Here, a=13, r=23 and n=9.

Sum of this finite geometric sequence is:

Sn=a(1rn1r)S9=(13

To determine

(b)

To find:

The sum 1+121/2+12+123/2+....
