Find the first six terms of the sequence. a1 = -4, an = an-1 + 7 -4, 3, 10, 17, 24, 31 -4, 7, 14, 21, 28, 35 3, 10, 17, 24, 31, 38 0, 7, 14, 21, 28, 35

A) -4, 3, 10, 17, 24, 31

Step-by-step explanation: To solve the given problem we need to calculate the first six terms of the sequence (starting with a1):

a1=-4

a2=a1+7

a2=-4+7

a2=3

a3=a2+7

a3=3+7

a3=10

a4=a3+7

a4=10+7

a4=17

a5=a4+7

a5=17+7

a5=24

a6=a5+7

a6=24+7

a6=31.

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
