Find the 100th and the nth term for each of the following sequences.80,140,200

Alina [70]

Answer

a(n) = 60n + 20

a(100) = 6020

Step-by-step explanation:

Given the following sequences

80, 140, 200

$\begin{gathered} \text{The given sequence is }80,\text{ 140, 200} \\ \text{Step 1: find the common difference} \\ \text{common difference= next term - previous term} \\ \text{Common difference = 140 - 80} \\ \text{Common difference = 60} \\ \text{common difference = 200 - 140} \\ \text{common difference = 60} \\ \text{Hence, the common difference is 60} \\ \text{The nth term of an arithmetic progression is} \\ a(n)\text{ = a + (n - 1) x d} \\ \text{where a = first term, n = no of terms, and d = common difference} \\ a(n)\text{ = 80 + (n - 1) x 60} \\ \text{open the parenthesis} \\ a(n)\text{ = 80 + 60n - 60} \\ a(n)\text{ = 60n + 80 - 60} \\ a(n)\text{ = 60n + 20} \\ \\ \text{ Find the 100th term} \\ \text{let n = 100} \\ a(100)\text{ = 60(100) + 20} \\ a(100)\text{ = 6000 +2}0 \\ a(100)\text{ = 6020} \end{gathered}$

Consider the sequence below. If we represent this sequence with the letter a then do the following

slamgirl [31]

Answer:

a(5)=25

a2+a6=44

a(4)+2a(6)=93

sqrta(5)=5

Step-by-step explanation:

You are given all the terms needed but sometimes you will have to create a formula.

a(b)=6b-5 is the formula in this sequence, now you can just plug in everything.

a(5)=6(5)-5

=25

a2=7

a6=37

7+37=44

a(4)=19, a(6)=37

19+2(37)=93

a(5)=25

sqrt25=5
