2(a - b) - (b - a) = 2a - 2b - b + a = 3a - 3b
Common difference r will be the difference between next two values of number row, so we take e.g. second minus first: r=9.4-6=3.4. You can see, that this value is constant as we go through next pairs of values.
Answer:
Step-by-step explanation:
A. The Ratio Test says that the series converges absolutely
Should be the first option.
Since ABP is congruent to CBP in the 4th step, AP must be equal to CP
