Find the 10th term of the geometric sequence 5, 25, 125,

Step-by-step explanation:

Geometric sequence 5, 25, 125,

First term = a = 5

Common ratio = r  = 2nd  term  ÷ first term

                       = 25 ÷ 5

                       = 5

n = 10

nth term = ar⁽ⁿ ⁻ ¹⁾

10th term = 5 * 5⁹

                = 5 * 1953125

                = 9765625

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
