2.2.2 Method to Implement: getIntermediateStats Problem. You are asked to implement a utility method which takes as inputs the first term (!), common difference (d), and size (n) of an arithmetic sequence. Based on these three input values, the corresponding arithmetic sequence of n terms) is: where t; = ft + (1 - 1).d and 1 : 23 ; avg of : 23.00], [sum of : 57 ; avg of : 28.50]} Todo. Implement the Utilities.getIntermediateStats method. See the comments there for the input paran- eters and requirements. The String return value must conform to expected format: All statistical terms are wrapped within curly braces (}) and separated by commas (.). Each statistical term is wrapped within square brackets ([]) and reports the sum and average of the corre- sponding sub-subsequence. Each sum is an integer and cach average should be formatted as a floating-point number with 2 digits after the decimal point, using String.format(%.2f, some Number), In the above example, the arithmetic sequence implied by the three input values (23, 11, and 2) is (23, 34), and the output string contains the statistical items for the two sub-sequences: (23) and (23, 34). As a slightly longer example, consider the statistical terms that should be included in the output string by input values 23 (first term), 11 (common difference), and 5 (size): [sun of 23 ; avg of : 23.00] [sum of : 57 ; avg of : 28.50] [sum of : 102 ; avg of : 34.00] [sum of : 158 ; avg of : 39.50] [sum of : 225 ; avg of : 45.00] All five statistical items above should be wrapped within curly braces ({}) and separated by commas (,). There is one space before and after the semicolon (;). There is one space after each commna (,) and colon (:)
