Solve for x&y
x+y=34
Log base 2 of x + log base 2 of y =6

Answers

Answer 1
Answer: x > 0; y > 0;
Log base 2 of x + log base 2 of y =6 <=> log base 2 ( xy) = 6 <=> xy = 64;
but, x + y = 34 => x = 32 and y = 2 or, x = 2 and y = 34.

What is the 50th term of the arithmetic sequence 4, 10, 16, 22, … ?Can someone explain this one?

Answers

The equation appropriate for this is
a_(n)=a_(1)+(n-1)d
Wherein _(n) is the missing term, a_(1) is the first number in the sequence, and d is the difference between the numbers.
Soa_(50)=4+(50-1)6
    a_(50)=4+(49*6)
    a_(50)=4+(294)
    a_(50)=298
*Sorry for the error.
298, also 4 is first term. 49 terms left. 49*6=294
294+4=298
