Construct a 3 x 4 matrix whose elements are

a_{i j} = i +J

Solution

Let A = [ a_ii] be required 3 x 4 matrix where a_ij= i + j
_{$therefore space space space$}a₁₁ = 1 + 1 = 2, a₁₂ =1+2, a₁₃=1 + 3 = 4, a₁₄ = 1 + 4 = 5
a₂₁ = 1 + 1 = 2, a₂₂ =1+2, a₂₃=1 + 3 = 4, a₂₄ = 1 + 4 = 6
a₃₁ = 1 + 1 = 2, a₃₂ =1+2, a₃₃=1 + 3 = 4, a₃₄ = 1 + 4 = 7

therefore space space space space straight A equals open square brackets table row 2 3 4 5 row 3 4 5 6 row 4 5 6 7 end table close square brackets
