WebJan 4, 2012 · For 2a+1, a 2 +a+1, and 3a 2-3a+3 to be the consecutive terms in an A.P. their common difference should be the same.. So, (a 2 +a+1) - (2a+1) = (3a 2-3a+3) - (a 2 +a+1). a 2 +a+1-2a-1 = 3a 2-3a+3-a 2-a-1. a 2 - a = 2a 2 - 4a + 2. a 2 - 3a + 2 = 0 (a - 2) (a - 1) = 0 a = 2 or a = 1 WebDetermine ‘a’ so that 2a+1, a^2+a+1 and 3a^2-3a+3 are consecutive terms of an A.P.#AP#CBSE #Mathematics#ArithmeticProgressions #FirstTerm #CommonDifference...

Solve Study Textbooks Guides Join / Login WebExample 1: For the given matrix below compute both det (A) and det (2A). Also verify the property det (cA) = cn det (A). Solution: First of all, we’ll find the scalar multiples of the given matrix. The determinants: det (A) = 45 det (2A) = 360 = (8) (45) = 23det (A) Hence the property is verified. Example 2: Let A be an n × n matrix. bayaran pemulih 2021
