Find the first term and the explicit formula a12=1/32 and r=1/2

Alexxx [7]

Answer:

see explanation

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Given $a_{12}$ = $\frac{1}{32}$ and r = $\frac{1}{2}$ , then

a $(\frac{1}{2}) ^{11}$ = $\frac{1}{32}$ , that is

$\frac{a}{2^{11} }$ = $\frac{1}{32}$

$\frac{a}{2048}$ = $\frac{1}{32}$ ( cross- multiply )

32a = 2048 ( divide both sides by 32 )

a = 64 ← first term

Thus the explicit formula is

$a_{n}$ = 64 $(\frac{1}{2}) ^{n-1}$
