Question

Find d of an A.P. whose first two terms are -3 and -4.​

Answer 1

Answer:

-1

Step-by-step explanation:

we know that, second term - first term = d

- 4 - ( -3) = d

- 4 + 3 = d

- 1 = d

I hope it will help you.

Answer 2

Answer:

Question

✳️Find d of an A.P. whose first two terms are -3 and -4.

Solution ⬇️

✍️Here : t1=(a)=-3 , t2=-4.. given

✍️To find : Common difference (d)=??

__________________________________

✍️by using Formula

✍️t2-t1=-4-(-3)=-4+3=-1

✍️ Therefore, common difference (d)=-1

• ❇️To find normal sum = Tn=a+(n-1)d
• ❇️To find common difference (d)=T2-T1
• ❇️To find consecutive integer = x,x+1,x+2
• ❇️To find sum= Sn=n/2[2a+(n-1)d]
