Question

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule. A (n)=1+(n-1)(-4.1)

A.)1, –15.4, –40
B.)–4.1, –15.4, –36.9
C.) 0, –12.3, –36.9
D.)1, –11.3, –35.9

Answer 1

A(1) = 1 + (1-1)(-4.1) = 1

A(1) = 1 + (4-1)(-4.1) = -11.3

A(1) = 1 + (10-1)(-4.1) = -35.9

Answer is D

Answer 2

The correct option is D.)1, –11.3, –35.9

What is AP?

Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value.

Given:

A (n)=1+(n-1)(-4.1)

n=1

A (1)=1+(1-1)(-4.1)

A(1)= 1

A (4)=1+(4-1)(-4.1)

A(4)= -11.3

A(10) = 1 + (10-1)(-4.1)

A(10) = -35.9
