Identify a2 in the sequence below , 12 , 7 , 2 , -3

a₂ = 7

Step-by-step explanation:

The subscript 2 on a₂ represents the second term in the sequence.

The second term is 7 , so

a₂ = 7

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
