Answer:
Your answer is correct. The series is a geometric series with common ratio -1/4 and first term 40. So each term is:
an = 40 (-1/4)^(n−1)
So the sum of the first 10 terms is:
∑(n=1 to 10) [ 40 (-1/4)^(n−1) ]
Let's first write all the factors of 168 and 252.
168 - <span>1,2,3,4,6,7,8,12,14,21,24,28,42,56,84,168</span>
252 - 1,2,3,4,6,7,9,12,14,18,21,28,36,42,63,84,126,252
84 is the GCF because 84 is greatest common factor of 168 and 252.
So, 84 is the GCF
Hope this helps.. :)
