Use the graph below to determine a1 and d for the sequence.
a1 = 1; d = 3
a1 = 1; d = −3
a1 = 2; d = 3
a1 = 2; d = −3
NEED HELP ASAP

a₁ = 2 and d = 3

Step-by-step explanation:

Consider the sequence given by the values of y, that is

2,  5,  8,  11,  14,  17

The first term in the sequence is a₁ = 2

The common difference is

d = 17 - 14 = 14 - 11 = 11 - 8 = 8 - 5 = 5 - 2 = 3

Thus a₁ = 2 and d = 3

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
