Step-by-step explanation:
1, 3, 5, 9, 15, 19, 19
Answer:
A)
Step-by-step explanation:
check that the formula in A works . . .
the 7th term should be 320
a(320) = 5(2)^7-1
= 5(2)^6
= 5(64)
= 320
1 step (B): raise both sides of the equation to the power of 2.
.
2 step (A): simplify to obtain the final radical term on one side of the equation.
.
3 step (F): raise both sides of the equation to the power of 2 again.
.
4 step (E): simplify to get a quadratic equation.
.
5 step (D): use the quadratic formula to find the values of x.
.
6 step (C): apply the zero product rule.
.
Additional 7 step: check these solutions, substituting into the initial equation.

Let's solve this using unitary method ~
