Write a possible explicit formula for the following sequence: -17, -22, -27, -32
an = ?

for sequence -17, -22,-27,-32

n = -17 - (n-1)5...eqn for sequence

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
