Find the nth term of 67,56,45,34

kvv77 [185]

Answer:

an = 67 -11(n -1)

Step-by-step explanation:

The terms of your arithmetic sequence have a common difference of -11. The first term is 67.

These values can be used in the generic formula for the n-th term:

an = a1 +d(n -1) . . . . . . first term a1, common difference d

an = 67 -11(n -1) . . . . . formula for the n-th term

What is the value of the fourth term in a geometric sequence for which a1= 30 and r = 1/2

Viktor [21]

Answer:

$a_{4}$ = 3.75

Step-by-step explanation:

The n th term of a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 30 and r = $\frac{1}{2}$ , thus

$a_{4}$ = 30 $(\frac{1}{2}) ^{3}$ = 30 × $\frac{1}{8}$ = $\frac{30}{8}$ = $\frac{15}{4}$ = 3.75
