three fifths. it can be 6/10. if you put one half in those terms of multiplying by 10 it would be 5/10.
-8-4-2-1-1/2-1/4-1/8
(Sum of terms)/(number of terms) (10+10+10+2)/4=8
The first three terms of the nth term 4n-2 would be obtained by plugging in n=1, n=2, and n=3 into the expression. Therefore, the first term would be 4(1) - 2 = 2, the second term would be 4(2) - 2 = 6, and the third term would be 4(3) - 2 = 10. So, the first three terms are 2, 6, and 10 for the given nth term 4n-2.
The pattern looks like the previous number is multiplied by -3, hence the next number in the sequence would be (-54) x (-3) = 162
