17(p+1)=29(q+1) --> (p+1)/(q+1) = 29/17 --> the least positive value of p+1 is 29, so the least value of p is 28 and the least positive value of q+1 is 17, so the least value of q is 16 --> the least value of p+q is 28+16=44.

17(p+1)=29(q+1)

$$\frac{p+1}{q+1} = \frac{29}{17}$$

$$\frac{29}{17}$$ cannot be simplified further as both are prime numbers

Equating numerator & denominator respectively

p+1 = 29; p = 28

q+1 = 17; q = 16

p+q = 44
