Questions and Mark Scheme 
1. i. The first three terms of an arithmetic progression are 2x, x + 4 and 2x − 7 respectively. Find 
the value of x. 
[3] 
ii. The first three terms of another sequence are also 2x, x + 4 and 2x − 7 respectively. 
a. Verify that when x = 8 the terms form a geometric progression and find the sum to 
infinity in this case. 
[4] 
b. Find the other possible value of x that also gives a geometric progression.
