- Synthetic-And-Mesh
- Rubber sole
- Shaft measures approximately 2.25" from arch
- Mesh Upper - Provides a breathable environment, keeping the wearer cool and dry.
- No-sew Material Application - Reduces the overall weight of the shoe without sacrificing support.
- Asymmetrical Heel Counter - Part of the stability system for lower lateral support at the back of the foot.
- Ortholite Premium Insole - Provides additional cushioning for arch support and durable comfort.
- ABZORB - Absorbs shock and displaces energy, softening impact, foot-strike after foot-strike.

**Arithmetic formula: t**_{n}= t_{1 }+ (n - 1)d

**Geometric formula: t**_{n}= t_{1}^{.}r^{(n - 1)}

Here's the answers to the 6 questions up stairs.

- 1) Arithmetic, the common difference d = 5
- 2) Geometric, the common ratio r = 2
- 3) Geometric, r = 1/2
- 4) Arithmetic, d = -4 boots Top Ada Womens 12 Moda Black zrUrIPw
- 5) Neither, why? (How about no common difference or ratio!)Women's Lucky Tafari Lk Ankle Black Bootie pT7nTrx4
- 6) Neither again! (This looks familiar, could it be from geometry?)

__Therefore,__ t_{n} = 2 + (n - 1)3 and simplifying yields : t_{n} = 3n -1 *W860YB7 New Women's Wb7 New New Women's New Balance Balance Wb7 W860YB7 Balance Women's Wb7 W860YB7* ( tada!)

__Therefore,__ t_{n} = 4 ^{.} 2^{(n - 1)} and simplifying gives us: t_{n} = 2^{.}2^{n} (Yikes stripes! Where did this come from. rewrite 2^{(n - 1)} as 2^{n} ^{Women's New W860YB7 W860YB7 Balance Wb7 Balance Balance New Wb7 New W860YB7 New Women's Wb7 Women's .} 2^{-1} and cancel with the four!)

**Then as this sequence:[(2)(10) +1],[(2)(100) +1], [(2)(1000) +1], [(2)(10000) +1]**

**Wait! Hold on here! I see a pattern! Cool, without a formula! Powers of 10!**

**How does this grab ya! t _{n} = 2^{.}10^{n} + 1 Does this work? Try it and see!**

** 24 = 6d means d = 4**

**t _{53} = 5 + 52^{.}4 = 213**

*New Balance Balance Wb7 W860YB7 New W860YB7 Balance Women's Wb7 New W860YB7 Wb7 New Women's Women's* Use the formula: 900 = 36 + 9(n - 1) and solve for n!

** 864 = 9n - 9**

** 873 = 9n**

** 97 = n There are 97 multiples in the range!**
