Q1 = 10, 22, 37, 64, 217, 334, 2134 = 7 (eg 10 = 2+1+3+4, 334 = (2+1)x100+3x10+4)
Q2 = 2x16, 3x15, 4x14, 5x13, 6x12, 7x11, 8x10 = 7 = 36/4-2 = n/4-2 (eg perimeter divided by number of sides misus the 2 solutions where the rectangle is a square or a straight line). n/4-1 if you allow a square as a rectangle.
Q3a =
Pour 3L into the 5L measure. Fill the 3L measure and use this to fill the 5L measure. 1L is left in the 3L measure. Pour the 5L back in the vat.
Q3b =
Pour 7L into the 10L measure. Fill the 7L measure and use this to fill the 10L measure leaving 4L in the 7L measure. Pour the 10L measure back in the vat. Pour the 4L into the 10L measure and fill the 7L measure. Fill the 10L meaasure from the 7L measure leaving 1L in the 7L measure. Pour the 10L measure back in the vat.
