Question

a=14,an=98,d=7 then n =​

Answer 1

Answer:

Step-by-step explanation:

as we know the formula,

an=a+(n-1)d

98=14+(n-1)7

98=14+7n-7

98=7+7n

7n=91

n=13

Answer 2

Answer:

n=7

Step-by-step explanation:

an=98

an=98 n=98/a

an=98 n=98/a n=98/14

an=98 n=98/a n=98/14 n=7

an=98 n=98/a n=98/14 n=7

an=98 n=98/a n=98/14 n=7 n=7
