Question

how many terms are their inA.P, -7,-4,-1,2...101​

Answer 1

Answer:your answer is 37

Step-by-step explanation:

we know that AP=-7,-4...101

from this we get a=-7,d=-4-(-7). d=-4+7. d=3 and an th term is 101

we need to find number of terms i.e. n

using general fromula of AP

an=a+(n-1)d

101=-7(n-1)3

101+7=(n-1)3

108=(n-1)3

108/3=n-1

36=n-1

37=n

your answer is 37
