unable to understand Consider two sequences with the first term of each of the series equal 16. One of these series follows arithmetic progression while the other follows geometric progression. The second terms of both the series are also the same. The third terms of both the series differ by 16. If the common difference series following the arithmetic progression is ‘d’ and the common ratio of the series following the geometric progression is ‘r’ such that d, r > 0 then (d + r) =
