Question

find the common difference and sum of 51 terms of an ap 1,3,5,7,....​

Answer 1

Answer: common difference=2; sum=102

Step-by-step explanation:

The common difference of an AP is the difference of two consecutive terms

3-1=5-3=7-5=common difference =2

The sum of “n” terms of an AP formula:

2a+(n-1)d [a= 1st term; n=number of terms; d=common difference]

Here the sum of the given AP is 2(1)+(51-1)2= 2+(50*2)= 2+100= 102

Hope this helps
