a) The first term of a geometric progression is 36. The sum of the first three terms is 27.
Calculate the common ratio and the value of the second term.
b) The first term of an AP is 2. The first term of a geometric sequence is also 2 and its common ratio
equals the common difference of the arithmetic sequence. The square of the fifth term of arithmetic
sequence exceeds the third term of the geometric sequence by 2. Find the common difference and the
sum of the first 50 terms of AP.
