Please help:
1.) Write the recursive formula {an = an – 1 + d} for the sequence: 1, 1.25, 1.50, 1.75, 2, 2.25, 2.50, 2.75, 3, 3.25
2.) Write the recursive formula {an = an – 1 + d} for the sequence: 1, 1.50, 2, 2.50, 3, 3.50, 4, 4.50, 5, 5.50
3.) Write the explicit formula {an = a1 + (n – 1) • d} for 1, 1.25, 1.50, 1.75, 2, 2.25, 2.50, 2.75, 3, 3.25
4.) Write the explicit formula {an = a1 + (n – 1) • d} for 1, 1.50, 2, 2.50, 3, 3.50, 4, 4.50, 5, 5.50
(The 'n' in all the 'an' is denoted {below the a} but I couldn't figure out how to do it and in the first two the 'n - 1' is also denoted and in the second two the '1' is denoted in the 'a1')
