Use the formula an = d (n − 1) + aj to write a formula for the arithmetic sequence below. 2, 6, 10, 14, 18,

= 4n - 2

Step-by-step explanation:

There is a common difference d between consecutive terms in the sequence, that is

6 - 2 = 10 - 6 = 14 - 10 = 18 - 14 = 4

This indicates the sequence is arithmetic with n th term

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 4 , thus

= 2 + 4(n - 1) = 2 + 4n - 4 = 4n - 2

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
