Step 1: Find the 1st common difference which is (10-7)=3, (15-10)=5, (22-15)=7. Since the 1st common difference is not constant then we need to find the second common difference Step 2: Find 2nd common difference (5-3)=2, (7-5)=2. Since we have a constant difference of 2 we divide it by 2 and multiply with a sequence of n^2 Step 3: sequence of (2/2)*n^2 So 1, 4, 9, 16 Then we subtract the new se... more

Alevels in Math and Physics are what applicants for pilot programmes or aeronautical-related jobs usually have. If you are strong in your math and sciences I would recommend you to take alevels from the following Math, Further maths, Physics, Chemistry Computer Science

A quadratic equation is of the form ax^2+bx+c=0 There are three ways to solve a quadratic equation: 1)Factorising- this is where you find two numbers that multiply to give c and add to give b ie. x^2+5x+6=0 the numbers 2 and 3 multiply to gove 6 and add to give 5 so we can put this equation into a factories form of (x+2)(x+3)=0 this means x=-2 and x=-3 are solutions to this equation. If the Equa... more
