For k+1, We see that the $ k+1$ th row has two 1's and the rest other values are made by adding the numbers of the kth row two times except the ones on the corners of the kth row. So the sum of the numbers except the two ones of the kth row is $2^k-2$. So the sum of the k +1 th row is $ 1 + 1 + 2(2^k -2) + 1 +1 = 2^{k+1}$.
