<h3>Answer:</h3>

\boxed{\bold{a_n = a_{n-1} -0.8}}

<h3>Explanation:</h3>

<u>Sequence</u>: 1.2, 0.4, -0.4, – 1.2, -2,...

See that with every next term, the integers are decreasing by 0.8

  • So, common difference (d) = -0.8

<u>recursive formula</u> : \sf a_n = a_{n-1}  +d

\bold a_1 = 1.2, \sf a_n = a_{n-1} + (-0.8)

When testing whether the correlation coefficient differs from zero, the value of the test statistic is t20=1.95 with a correspon
expeople1 [14]
Given:
value of the test statistic is t20 = 1.95
corresponding p-value of 0.0653 at the 5% significance level

No, I can't conclude that the correlation coefficient differs from zero because the p-value, which is 0.0653 exceeds 0.05. 

The correlation coefficient differs from zero when the p-value is less than 0.05.
