What our users say

Who ever made this, u are a legend. Just snap a pic, send it through, tell them how you want it to be solved, and BAM. It's absolutely amazing. The in app keyboard could not be more user friendly. If you get the plus subscription it gets better.

Although, one thing is that you have to watch videos to see the steps of the problems but it gives you the answer for free. I use this to solve an algebra that I forgot how to do it, and this app literally shows every steps to get the answer. Please sir, add Bangla language. This is the complete mathematical package I need as a student.

It always get the questions correct and my grade goes up. Only thing I would like to be different is to be able to scan graphs, thank you. You can even take photo of sum or record audio as question, this helps me for understanding the math problems, It's very useful! But There are Some things that app can't solve, but I'm okay with that, they said they'll have to update it soon so their app will be very useful than the other apps, download this now! But remember don't cheat on exam lol.

What is Common Ratio Formula?Examples

We know that in a geometric sequence, a term (a n) is obtained by multiplying its previous term (a n - 1) by the common ratio (r). So by the recursive formula of a geometric sequence, the n th

Geometric Sequences and Sums

S_n = a [ (r^n-1)/ (r-1)] if r > 1 and r ≠ 1. S_n = a [ (1 – r^n)/ (1 – r)] if r the common ratio is r = l / [r (n – 1)]. The sum of infinite

Terms of Geometric Sequences

This means that the common ratio of this geometric sequence is 3. To find the next two terms, we simply multiply 18 by 3 and do the same for the next term. 18 × 3 = 54 54 × 3 = 162. Now
