Answer 1

Heya....☺

Here's ur ans. ⬇


⚫. an =a+(n-1) d.

where an = nth term , a = first term , n= term no. , d = coming difference

◾ a2 = 71/2 + (2-1) × 11/2
a2 = 71/2 + 11/2
a2 = 82/2
↪ a2 = 41


◾ a3 = 71/2 + (3-1) × 11/2
a3 = 71/2 + 11
↪a3 = 83/2

◾ a4 = 71/2 + (4-1) × 11/2
a4 = 71/2 + 33/2
a4 = 104/2
↪a4 = 52

◾ a5 = 71/2 + (5-1) × 11/2
a5 = 71/2 + 44/2
↪ a5 = 115/2
