Find the next term in the alpha-numeric series:
$$\text{Z1A},\text{X2D},\text{V6G},\text{T21J},\text{R88M},\text{P445P},?$$

Let us break down the series into its individual components:
1. First Letter: Decreases by 2 alphabetical positions:

$$\text{Z}(26)\to \text{X}(24)\to \text{V}(22)\to \text{T}(20)\to \text{R}(18)\to \text{P}(16)\to \text{N}(14)$$

2. Middle Number: Follows a progressive multiplication and addition pattern:
* $1\times 1+1=2$
* $2\times 2+2=6$
* $6\times 3+3=21$
* $21\times 4+4=88$
* $88\times 5+5=445$
* $445\times 6+6=2670+6=2676$

3. Last Letter: Increases by 3 alphabetical positions:

$$\text{A}(1)\to \text{D}(4)\to \text{G}(7)\to \text{J}(10)\to \text{M}(13)\to \text{P}(16)\to \text{S}(19)$$

Putting the components together, we get $\text{N2676S}$.
