Will mark brainliest! in a geometric sequence {an}, if a1 = 4 and r = 0.2, the first 4 terms in the sequence a) {4, .8, .16, .}. b) {4, 20, 100, }. c) {4, 4.2, 4.4, 4.}. d) {4, 3.8, 3.6, 3.}.

A.) {4,.8,.16,.032,...}

Begin with 4 and multiply by 0.2, the ratio, to obtain successive term.

The first 4 terms in the sequence are...

A) {4, .8, .16, .032,...}.

Further explanation

Geometry sequence are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

where:

a is the first term, and

r is the common ratio

In an geometric sequence , if a1 = 4 and r = 0.2, the first 4 terms in the sequence are

n=1

n=2

n=3

n=4

The distances are equivalent; the distances from first to second base and second to third base are the same value, the angles formed by first and second base and home plate are the same degree as third and second base and home plate. The two angles are complementary adjacent angles, meaning they share the same side and vertex and equal 90°. This information can be used to infer that we are identifying a square, so the distance from first to home and home to third must be equivalent, as squares have the same length for each side.
