In the sequence, we are given with -2, 8, -32...This is a geometric type of sequence with a geometric ratio of 4. a1 is equal to -2 and r is equal to 4The expression is
a n = a1 * r ^ (n-1) where n is an integer ora n = a1 * (-4) ^ (n-1)we can check or verify this using the given

What's 3 over 10 times 1over 6 ?

velikii [3]

$\frac{3}{10}$ × $\frac{1}{6}$
To multiply, you multiply across. So it would be 3×1=3 and 10×6=60
Which will result in $\frac{3}{60}$ but in order to simplify it, you find a common factor. The common factor is 3. 3÷3=1 and 60÷3=20
The answer is $\frac{1}{20}$
