Find the sum of the geometric series 1+2+4+… …7 terms

1 + 2 + 4 + 7 + 11 + 16 + 22 + 29 + 37 + 46

I may have given more. I think it was like this.

You add one to 1 and you get two. Then add two to 2 and you get four and then add three to 4 and then there is 7. I think this is how it goes.

I hope you understood :)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
