Answer:
It’s 10n+12
They put the 2 n’s as an exponent
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
From your knowledge of multiplication tables, you know that ...
-35 = -(7×5) = 7×(-5)
Then comparing to the given equation, you realize ...
t = -5
_____
Or, you can recognize 7 as the coefficient of t and divide both sides of the equation by that:
-35/7 = (7t)/7
-5 = t
A geometric sequence is generated by multiplying the first term in the sequence, , several times by a fixed scalar . So
and so on, down to
Using the result above, the sequences you're interested in are
31)
33)
We can rewrite these results to make them slightly cleaner.
