i hope this question gets solved.

Task 1 [Arithmetic Progression (AP)] 1.1 A tensile test experiment conducted in the laboratory gave the following variations in readings: The first, tenth and the last terms of the readings follows an arithmetic progression of 9, 40.5 and 425.5 respectively. Find: (a) The number of terms (b) The sum of all the terms (c) The 751" term or reading if the experiment is extended. 1.2 An oil company bores a hole 900 metres deep. The rig is shown below. Determine using (AP) the cost of boring if the cost is 40 for drilling the rst metre, with an increase in cost of 3 per metre for succeeding metres. Task 2 [Geometric Progression (GP)] 2.1 The value of a metal forming machine originally valued at 5,450.00 depreciates 12% per annum. Use (GP) to determine its value after 9 years. correct to the nearest pounds. 2.2 A model of a Variable 4 Speed Pulley shown below is to be re-design to be used in a drilling machine to have 6 speeds ranging from, 150 rev/min to 1000 rev/min. if the speeds form a Geometric Progression; determine their values, each correct to the nearest whole number
