Let the sequence {an} be defined so that a1 = 1 and each succeeding term is found by multiplying the one before it by 4. find the formula representing an, the nth term of the sequence.

Step-by-step explanation:

When each term is multiplied by a number to get the next term, it is a geometric sequence.

The general term (nth term) of a geometric sequence is given by the formula:

Where is the first term and r is the common ratio (the number which is multiplied with a term to get the next term)

Now plugging in these into the formula gives us:

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
