Explanation Given information: The time she spent on life cycleis 15 minutes . She increases her riding time by 5 minutes every week. Calculations: Here the increase in time of the riding follows a arithmetic sequence. The general term of aarithmetic sequence is given by the equation, a n = a 1 + ( n − 1 ) d Where, a 1 = first term . d = common difference . Here the first term( a 1 ) is 15 minutes and the common difference is 5 minutes . . Putting all the values in the equation, a n = a 1 + ( n − 1 ) d ⇒ a n = 15 + ( n − 1 ) 5 The riding time after the seventh week will be given by the 8 t h term. Now the eighth term of the sequence can be calculated by putting the value of n = 8 in the equation

Let matrix A have order (dimension) 2x4 and let matrix B have order (dimension) 4x4. What results when you compute A+B? The resulting matrix will have dimensions of 2x4. ○ The resulting matrix will be a single number (scalar). The resulting matrix will have dimensions of 4x4. A+B is undefined since matrix A and B do not have the same dimensions.
